Question

triangle xyz is rotated 90° counterclockwise about the origin to form triangle kjl as shown below. which angle in triangle kjl must measure the same as ∠y? a. ∠j b. ∠k c. ∠l d. ∠z

Explanation:

Step1: Recall rotation property

When a figure is rotated, corresponding angles are congruent. Triangle XYZ is rotated 90° counter - clockwise about the origin to form triangle KJL.

Step2: Identify corresponding angles

Angle Y in triangle XYZ corresponds to angle J in triangle KJL.

Answer:

A. ∠J
