Sure! Here's a clear and concise answer to the question:
An angle that measures between 90° and 180° is called an obtuse angle. This type of angle is greater than 90 degrees but less than 180 degrees. To provide some context:
- A right angle measures exactly 90°, like the corner of a square.
- An acute angle is less than 90°, like the angles in an equilateral triangle.
- A straight angle measures exactly 180°, like a straight line.
- An obtuse angle is greater than 90° but less than 180°, like the angle formed by the hour and minute hands at 3 o'clock.
Therefore, in this case, the correct answer is:
D. Obtuse
