# What is an acute obtuse and reflex angle?

## What is an acute obtuse and reflex angle?

An angle less than 90° is acute. An angle between 90° and 180° is obtuse. An angle greater than 180° is reflex. An angle of exactly 90° is a right-angle.

## What is a reflex angle in geometry?

noun Geometry. an angle greater than 180° and less than 360°.

What is acute angle and obtuse angle with example?

Obtuse angles measure more than 90° (but less than 180°), and acute angles measure less than 90°. For example, 110° is an obtuse angle and 50° is an acute angle.

### How do you tell if an angle is acute or obtuse?

An acute angle is an angle that is less than 90°. It is smaller than a right angle, and it doesn’t matter whether this is 1° or 89°, it is still an acute angle. But angles can of course be bigger than 90°. An angle that is larger than 90°, but smaller than 180° is called an obtuse angle.

### What is a acute angle?

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

What is acute angle example?

An angle which is measuring less than 90 degrees is called an acute angle. This angle is smaller than the right angle (which is equal to 90 degrees). For example, ∠30o, ∠45o, ∠60o, ∠75o, ∠33o, ∠55o, ∠85o, etc. are all acute angles.

#### What is a obtuse angle in geometry?

An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees.

#### What is the definition of obtuse angle?

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

What is the definition of an obtuse angle?

## How do you describe an obtuse angle?

an angle greater than 90° but less than 180°.

## What is obtuse angle with example?

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.

What is an obtuse angle definition?

### What is the difference between acute and obtuse?

In context|geometry|lang=en terms the difference between acute and obtuse is that acute is (geometry) of a triangle, having all three interior angles measuring less than 90 degrees while obtuse is (geometry) of a triangle: with one obtuse angle. is that acute is urgent while obtuse is blunt; not sharp. is (orthography) an acute accent.

### Which angles are obtuse?

Obtuse angle. A obtuse angle is an angle of greater than 90° and less than 180°. It is bigger than an acute angle. It is smaller than a straight angle, which measures 180°. Angles are measured with a protractor .

How do you find the acute angle?

To measure an angle, we use a tool called a protractor. When you line up the bottom line of the protractor on one of the angle lines and put the hole that is in the center bottom of the protractor on the corner of the angle, you can find the measure of the angle. Any measure less than 90° is an acute angle.

#### What is an obtuse acute?

Obtuse, which comes to us from the Latin word obtusus, meaning “dull” or “blunt,” can describe an angle that is not acute or a person who is mentally “dull” or slow of mind. The word has also developed a somewhat controversial sense of “hard to comprehend,” probably as a result of confusion with abstruse.
