How to Determine X and Y Using Congruent Triangles

The video tutorial explains how to determine congruent parts in triangles, emphasizing the importance of following directions rather than making assumptions based on appearance. It covers identifying congruent angles and setting up equations to solve for unknown variables Y and X, using congruence properties.

What should you not assume about congruent triangles based on their appearance?

• That they are drawn to scale

• That they are in the same orientation

• That they are identical in shape and size

• That they have the same color

In the context of congruent triangles, what is the correct relationship between angles A and D?

• Angle A is larger than angle D

• Angle A is congruent to angle D

• Angle A is smaller than angle D

• Angle A is unrelated to angle D

How do you solve for Y in the equation 8Y - 5 = 99?

• Divide both sides by 8, then add 5

• Multiply both sides by 8, then subtract 5

• Add 5 to both sides, then divide by 8

• Subtract 5 from both sides, then divide by 8

What is the value of Y when 8Y - 5 = 99?

• 12

• 13

• 14

• 15

How do you find the value of X if 2Y + X = 14 and Y = 13?

• Multiply 14 by 2

• Add 26 to 14

• Divide 14 by 2

• Subtract 26 from 14
