# What is benchmark angle?

## What is benchmark angle?

more Angles such as 30°, 45°, 60°, 90°, 180°, etc, that can be used as references.

### What are the angles of acute angles?

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.

What type of angle is 235 degrees?

Obtuse Angle: An angle whose measure is greater than 90° but less than 180° is called an obtuse angle. In other words, an angle measuring between 90° to 180° is called an obtuse angle. ∠DOQ shown in the above figure is an obtuse angle.

Which is an example of a related acute angle?

The related acute is an acute angle (#<90^@#) that can be found between the terminal arm and the x-axis when the terminal arm is in quadrants 2, 3, or 4. There is no related acute angle if the terminal arm lies in quadrant 1. Here are some examples:

## Is there related acute angle if terminal arm lies in Quadrant 1?

There is no related acute angle if the terminal arm lies in quadrant 1. Here are some examples: If the terminal arm is in quadrant 2, do 180^@ minus the principle angle to find the related acute angle. If the terminal arm is in quadrant 3, do the principle angle minus 180^@ to find the related acute angle.

### Which is an angle smaller than the right angle?

An angle smaller than the right angle is called an acute angle. In other words, the angle which is less than 90 degrees forms an acute angle. The polygons such as triangle, parallelogram, trapezoid, etc. consist of at least one acute angle in it.

Are there two acute angles and two obtuse angles?

A parallelogram has two acute angles and two obtuse angles. Therefore, the acute and obtuse angles should have the equal measurement. A trapezoid is a parallelogram with one pair of opposite sides being parallel.
