Properties of Isosceles and Equilateral Triangles
Skill Practice!
Refer to the figure.
1. If AC ≅ AD, name two congruent angles.
2. If BE ≅ BC, name two congruent angles.
3. If ∠EBA ≅ ∠EAB, name two congruent segments.
4. If ∠CED ≅ ∠CDE, name two congruent segments.
△ABF is isosceles, △CDF is equilateral, and m∠AFD = 150. Find each measure.
5. m∠CFD 6. m∠AFB
7. m∠ABF 8. m∠A
In the figure, PL ≅ RL and LR ≅ BR.
9. If m∠RLP = 100, find m∠BRL.
10. If m∠LPR = 34, find m∠B.
