Question

what fraction of a turn is this angle? 1/4 turn 3/4 turn 1/2 turn 1 full turn

Explanation:

Step1: Recall full - turn angle

A full - turn is 360 degrees.

Step2: Analyze the given angle

The given angle is a right - angle, which is 90 degrees.

Step3: Calculate the fraction

To find the fraction of a turn, we divide the given angle by the full - turn angle. So, $\frac{90}{360}=\frac{1}{4}$.

Answer:

$\frac{1}{4}$ turn
