Using corresponding parts of congruent triangles to find the missing value

The video tutorial explains the concept of congruent polygons, focusing on polygons ABCD and PQRS. It discusses the importance of corresponding angles and sides, demonstrating how to solve for unknown variables X and Y using these properties. The tutorial emphasizes the need to maintain the order of vertices when naming congruent polygons.

What is the relationship between the angles of congruent polygons?

• They are unrelated.

• They are supplementary.

• They are equal in measure.

• They are always complementary.

If angle A is represented as 2X + 4 and angle P is 100, what is the value of X?

• 50

• 52

• 48

• 46

Which side corresponds to CD in the congruent polygon PQRS?

• SP

• PQ

• RS

• QR

If 3Y - 3 equals 12, what is the value of Y?

• 6

• 5

• 7

• 4

When naming corresponding sides in congruent polygons, what must be true?

• They can be named in any order.

• They must be named in reverse order.

• They must be named in the same order.

• They must be named alphabetically.
