## What You Need To Know...

Congruent or similar triangles and the concept of corresponding parts of congruent triangles.

1. The benchmark will be assessed using MC (Multiple Choice) items.
2. Items will require the use of geometric properties to justify measures and characteristics of triangles.
3. Items may be set in either real-world or mathematical contexts.

## Example One

Nancy wrote a proof about the figure shown below.

In the proof below, Nancy started with the fact that  is a perpendicular bisector of  and proved that   WYZ is isosceles.

Which of the following correctly replaces the question mark in Nancy's proof?

1. ASA
2. SAA
3. SAS
4. SSS
