Question

which pair of angles shares ray af as a common side?
∠daf and ∠dab
∠eaf and ∠cae
∠baf and ∠ead
∠baf and ∠fad

Explanation:

Step1: Analyze angle - side relationship

An angle is formed by two rays with a common endpoint. We need to find the pair of angles that have ray AF as one of their rays.

Step2: Check each option

• For ∠DAF and ∠DAB, the common side is AD, not AF.
• For ∠EAF and ∠CAE, the common side is AE, not AF.
• For ∠BAF and ∠EAD, they do not have a common side.
• For ∠BAF and ∠FAD, ray AF is a common side for both angles.

Answer:

∠BAF and ∠FAD
