Question

In the given figure, $\angle BAC$ and $\angle CAD$ are adjacent angles. Find the common vertex and common arm.

• A. Common vertex A and common arm AB
• B. Common vertex B and common arm AB
• C. Common vertex A and common arm AC
• D. Common vertex C and common arm AC

Answer 1

The correct option is C Common vertex A and common arm AC


We know that adjacent angles share a common arm and a common vertex, and the non common arms will be on different sides of the common arm.

In the given figure, $\angle$BAC and $\angle$CAD have
common vertex: A
common arm: AC
non common arms: AB and AD
