Question

angle model possible measures

angle	acute	right	obtuse	straight
possible measures	(0^{circ}<a^{circ}<90^{circ})	(a^{circ}=90^{circ})	(90^{circ}<a^{circ}<180^{circ})	(a^{circ}=180^{circ})

classify each angle as acute, right, obtuse, or straight.

1. (angle nmp)

1. (angle qmn)

1. (angle pmq)

Explanation:

Step1: Analyze ∠NMP

It is greater than 90° and less than 180°.

Step2: Analyze ∠QMN

It has a right - angle symbol, so it is 90°.

Step3: Analyze ∠PMQ

It is less than 90°.

Answer:

1. obtuse
2. right
3. acute
