Prove that two isosceles triangles are similar if any angle of one equals the corresponding angle of the other.

a. Case 1: Equal Vertex Angles

Given: Isosceles$\u2206ABC$ , isosceles $\u2206DEF,AC=BC,DF=EF,\angle C=\angle F$

Prove: $\mathrm{\u25b3}ABC\sim \mathrm{\u25b3}DEF$

Statementc

1.(see above)

2.

3.$\mathrm{\u25b3}ABC\sim \mathrm{\u25b3}DEF$

Reasons

1.Given

2. Isosceles triangles with equal vertex angles have equal base angles also.(ex. 2.14 #5)

3. ?
