Question

m∠abc = 90°
what type of angle is it?
obtuse
straight
right
acute

Explanation:

An angle of \(90^{\circ}\) is defined as a right angle. An obtuse angle is greater than \(90^{\circ}\) but less than \(180^{\circ}\), a straight angle is \(180^{\circ}\), and an acute angle is less than \(90^{\circ}\). So, \(m\angle ABC = 90^{\circ}\) is a right angle.

Answer:

C. right
