Answer

the base angles are equal:

Part (a): Given: $AB = AC$ and $PQ = PR$ . Prove: $\frac{BD}{AC} = \frac{DR}{AQ}$ .

Step 1: Identify equal angles from the given information. Since $AB = AC$ , $\triangle ABC$ is an isosceles triangle. Therefore, the base angles are equal: $\angle ABC = \angle ACB$ Let $\angle ABC = \angle ACB = \beta$ .

Since $PQ = PR$ , $\triangle PQR$ is an isosceles triangle. Therefore, the base angles are equal: $\angle PQR = \angle PRQ$ Let $\angle PQR = \angle PRQ = \alpha$ . Note that $\angle PQR$ is the same as
