Question

Find the missing angles of the following isosceles triangles

Answer 1

Answer:

1 - 40° & 40°

2- 110° & 35°

3- 40° & 40°

4- 110° & 35°

5- 80° & 80°

Answer 2

1. QPC = QRC = 40°

2. EDF = DFE = 72.5°

3. QPC = QRC = 40°

4. EDF = DFE = 72.5°

5. ACB = ABC = 80°

Reason: Property of isosceles ∆ (Corresponding angles are equal) and the sum of the angles of a ∆ is 180°.
