Question

question 2 points 1
an angle whose measure is greater than 0° and less than 90° is called ______.
○ right angle
○ straight angle
○ acute angle
○ reflex angle

Explanation:

To solve this, we recall the definitions of each angle type:

• A right angle measures exactly \(90^\circ\).
• A straight angle measures exactly \(180^\circ\).
• An acute angle is defined as an angle whose measure is greater than \(0^\circ\) and less than \(90^\circ\).
• A reflex angle measures greater than \(180^\circ\) and less than \(360^\circ\).

From these definitions, the angle with measure between \(0^\circ\) and \(90^\circ\) is an acute angle.

Answer:

C. acute angle
