Question

Draw a rough diagram of two angles such that they have three points in common.

Answer 1

Step 1: Draw a ray $\overrightarrow{OA}$

Step 2: Draw a ray $\overrightarrow{OC}$

Step 3: Draw a ray $\overrightarrow{OB}$ in between $\overrightarrow{OA}$ and $\overrightarrow{OC}$

Step 4: Plot a point $D$ on the ray $\overrightarrow{OB}$

Hence, $\angle AOB$ and $\angle BOC$ are two angles such that they have three points in common that is $O$, $D$ and $B$.
