1. Triangle Congruence by SSS and SAS
Geometry 2.0 – Students write geometric proofs.
Geometry 5.0 – Students prove that triangles are congruent.

2. Example 1 Given: M is the midpoint of XY, AX = AY Prove: AMX = AMY
Statements
Reasons
1. AX = AY 1. Given
2. XM = MY 2. Given
3. AM = AM 3. Reflexive Property
4. AMX = AMY 4. Side- Side-Side (SSS)

3. Example 2 Given: RSG =RSH, SG = SH.
From the information given, can you prove RSG = RSH? Explain.
Statements
Reasons
1. <RSG = <RSH 1. Given
