Question

2 name the shaded angle in as many ways as possible.
a $\angle 2$
b $\angle lak$
c $\angle a$
d $\angle kal$
e $\angle 1$

Explanation:

• $\angle 2$ directly labels the shaded angle.
• $\angle KAL$ uses the vertex $A$ between points $K$ and $L$, matching the shaded angle's sides.
• $\angle LAK$ reverses the order of the side points with vertex $A$ in the middle, which is also valid for naming the angle.
• $\angle A$ is ambiguous because point $A$ is the vertex of two distinct angles ($\angle 1$ and $\angle 2$), so it cannot uniquely name the shaded angle. $\angle 1$ labels the unshaded angle, so it is incorrect.

Answer:

A. $\angle 2$, B. $\angle LAK$, D. $\angle KAL$
