## What is a acute right obtuse?

Acute Angle – An angle less than 90 degrees. Right Angle – An angle that is exactly 90 degrees. Obtuse Angle – An angle more than 90 degrees and less than 180 degrees. Reflex Angle – An angle greater than 180 degrees and less than 360 degrees.

How do you determine if an angle is acute obtuse or right?

An acute angle measures less than 90°, but more than 0°. A right angle measures exactly 90°. An obtuse angle measures more than 90°, but less than 180°. A straight angle measures exactly 180°.

### Is a 45 angle acute obtuse or right?

An acute angle is less than the right angle. The obtuse angle is greater than the right angle but smaller than the straight angle. A reflex angle is greater than a straight angle. a) Since 45 degrees is less than the right angle, it is an acute angle.

### What is mean by obtuse angle?

1a : not pointed or acute : blunt. b(1) of an angle : exceeding 90 degrees but less than 180 degrees.

What is an example of an obtuse angle?

Examples of Obtuse Angles We know that angles measuring greater than 90° and less than 180° are called obtuse angles. Therefore, angles that measure 145°,150°,178°,149°, 91° are considered as obtuse angle examples.

## Is 75 right acute or obtuse?

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees.

## How do you identify an obtuse angle?

An obtuse angle is any angle larger than 90 degrees and less than 180 degrees. In other words, if the angle formed where two line segments meet goes beyond a right angle, it’s obtuse. Think of it as a reclined car seat. Anything beyond that perfect upright, 90 degree position is obtuse.

Which of the following angle is obtuse?

### What is an example of obtuse?

Intellectually dull or dim-witted. The definition of obtuse is something that isn’t sharp. An example of obtuse is a child’s pair of scissors. In mathematics, an angle greater than 90 degrees, but less than 180 degrees.
