Because we are saying that the angles/edges in corresponding positions for each triangle are congruent.
Consider the triangle congruence statement below:
△ABC≅△DEFThis is actually a collection of six—yes, six—congruence statements.
They are as follows:
∠A≅∠D∠B≅∠E∠C≅∠FAB≅DEAC≅DFBC≅EFAs an example, consider the first congruence: ∠A≅∠D
This is implied by the fact that A and D are both listed first in their triangles (in the statement △ABC≅△DEF ). Similarly, B and E are in second place, so that's how we get ∠B≅∠E.A similar logic applies to the sides that have corresponding vertices.If the triangle congruence statement was as follows:
△ABC≅△FED
Then,
∠A would-be congruent to ∠F∠B would be congruent to ∠E∠C would be congruent to ∠DWe can see how changing the order of the triangle names changes which angles/edges are implied to be congruent.
This is why we must be cautious to name the triangles in the correct order. Otherwise, we risk claiming that two angles (or line segments) are congruent when they are not.Therefore, we are saying that the angles/edges in corresponding positions for each triangle are congruent.

Solve this multi-step problem. A runner completes of a 5-mile race every 8 minutes. At the same pace, how far can the runner go in 16 minutes?
The runner completes a 10 miles race in 16 minutes.
According to the question we have been given that,
Runner takes 8 minutes to complete = 5 miles race
We need to find that if the runner is in the same pace then how many miles the runner completes in 16 minutes
This multi-step problem can be solved using the unitary method. That is,
8 minutes = 5 miles
1 minute = 5/8 miles
16 minutes = 5/8*16 miles
= 5*2 miles
= 10 miles
Hence runner completes a 10miles race in 16 minutes

in straightedge and compass construction of the parallel line below which of the following reasons can you use to prove that JK and LN are parallel
The correct option is (C) ∠ MJK ≅ ∠ MKJ by construction.
When two parallel lines have a transversal cutting those parallel lines, the alternate angle theorem holds true. According to the alternate angle theorem, all alternate angles are equal.
We have a similar circumstance here, where we are employing the alternate angle theorem approach to design and build two parallel lines. To prove that the two alternate angles are equal and the lines are parallel, we must first identify the two alternate angles.
The two alternate angles are:
∠ MLN and ∠ MJK
Therefore, for the lines, JK and LN to be parallel the two angles must be congruent.

How can triangle classifications help you prove triangle congruence?
Triangle classification will always help us to prove congruency in triangle. Each of the three angles in an acute triangle is acute. One right angle and two acute angles make up a right triangle. Additionally, an obtuse triangle has two acute angles and one obtuse angle.
What is triangle congruence?The triangles are congruent when two sets of corresponding sides and the corresponding angles between them are in agreement. Two triangles that have a congruent angle in the middle and two congruent sides.
Instead of using the unit measure, it is based on the proportion of the side lengths to one another. As a result, triangles are categorized according to how many of their sides are the same length as one another or not at all equal.
Angles are another way to categorize triangles. Each of the three angles in an acute triangle is acute (less than 90 degrees). One right angle and two acute angles make up a right triangle. Additionally, an obtuse triangle has two acute angles and one obtuse angle (greater than 90 degrees).

Noor needs to build a pen for her chickens. She wants the pen to be rectangular, 3 meters longer than it is wide. Write the equation Noor should use to determine the width of a pen which has an area of 70 square meters
Given the area, the equation that Noor should use to determine the width of pen is x² + 3x = 70.
The length and width of the rectangular pen are 10m and 7m respectively.
What is the width of the rectangular pen?The area of a rectangle is expressed as;
A = l × w
Where l is length and w is width.
Given the data in the question;
Let the width of the rectangular pen be 'x'
Width = w = xLength = l = x + 3Area = 70m²To determine the equation that Noor will use to find the width of the pen, plug the values into the equation above.
A = l × w
70 = (x+3) × x
70 = x² + 3x
x² + 3x = 70
We can go further and solve for the width of the pen.
x² + 3x = 70
x² + 3x - 70 = 0
Factor sing AC method; find two integer whose addition gives 3 and multiplication gives -70.

Answer:
1) y = 6
2) Paul has 20 quarters
Step-by-step explanation:
y varies directly with x .
If y=6 when x=2 , find x when y=12 .
The required value of x is 4 by using constant of proportion.
What is the constant of proportion?
A constant of proportion is illustrated as the ratio which relates two given quantities with each other in the relationship of proportion. Constant of proportion is also called constant variation, rate of change, and constant ratio.
Solving for the value of y
When a quantity varies directly with others, then we have a relation, y = kx, where k is the constant of the proportion —-- 1
Now, find k for given x = 2 and y = 6, we need to put these values in equation 1, i.e.
6 = k(2)
k = 6/2
k = 3
Further calculate x for given y = 12 and constant of variation = 3 i.e.
12 = (3)x
x = 4
Hence, the required value of x is 4.

x · y = 54 (1)
2 · (x + y) = 30 (2)
By (2):
2 · x + 2 · y = 30
2 · x = 30 - 2 · y
x = 15 - y
(2) in (1):
(15 - y) · y = 54
15 · y - y² = 54
y² - 15 · y + 54 = 0

Baca weighs 218 pounds and gains 0.2 pounds of muscle per week. Create an equation that Luis and Baca can use to determine how long it will take for them to be the same weight. In the text box, write about how you formed the equation used to determine when Luis and Baca would be the same weight. BI
Luis and Baca would be the same weight after 60 weeks of weightlifting.
What is a linear Equation?A linear equation is one in which the highest power of the variable is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation.
To create an equation that Luis and Baca can use to determine how long it will take for them to be the same weight:
Let the time taken by Luis and Baca to be of the same weight be x weeks,
Given:
Initial weight of Luis = 194 pounds
Initial weight of Baca = 218 pounds
Then,
Weight gained by Luis in x weeks = 0.6x pounds
Weight gained by Baca in x weeks = 0.2x pounds
Total weight of Luis after x weeks = (194 + 0.6x ) pounds
Total weight of Baca after x weeks = (218 + 0.2x) pounds
For Luis and Baca to be of the same weight,
Total weight of Luis after x weeks = Total weight of Baca after x weeks
Therefore, we equate the total weight gained by Luis and Baca after x weeks to determine the value of x
⇒ 194 + 0.6x = 218 + 0.2x
⇒ 0.6x - 0.2x =218 - 194
⇒ 0.4x = 24
⇒ x = 60
Hence, Luis and Baca would be the same weight after 60 weeks of weightlifting.
