Example 3 Choosing a Congruence Postulate to Use Decide whether enough information is given in the diagram to prove that AWYZ = AZXW. If there is enough information, state the congruence postulate you would use. W Solution Paragraph Proof The marks on the diagram show that and By the Alternate Interior Angles . By the Reflexive Property of Postulate, Congruence, angle of AWYZ are congruent to the corresponding two sides and included angle of AZXW, you can use the Because two sides and the included to prove that the triangles are congruent.

Triangle ABC is translated and then reflected to map triangle A”B”C” as shown. Which of the following postulates or theorems proves the triangles congruent? ANSWER CHOICES / Diagram ARE IN THE PHOTO.

If n represents any integer, then an expression representing all angles coterminal with 120° is 120° + If n represents any integer, then an expression representing all angles coterminal with 120° is 120° + (Type an equation using n as the variable.)
