Question

which of the following represent an acute angle drawn in the figure below? ∠plk ∠mlj ∠jol ∠rlm

Explanation:

Step1: Recall acute - angle definition

An acute angle is an angle whose measure is between 0° and 90°.

Step2: Analyze each angle

• For $\angle PLK$: It appears to be an obtuse - angle (greater than 90°).
• For $\angle MLJ$: It is a straight - angle (equal to 180°).
• For $\angle JOL$: It is a right - angle (equal to 90°).
• For $\angle RLM$: It is an acute - angle as it is less than 90°.

Answer:

RLM
