There are

**four main types of angles**: right**angles**, acute**angles**, obtuse**angles**, and straight**angles**. Right**angles**are like corners and measure 90°. Acute**angles**are smaller than 90°. Obtuse**angles**are larger than 90°, but less than 180°.Furthermore, what are the 5 types of angles?

**Types of Angles - Acute, Right, Obtuse, Straight and Reflex**

- Acute angle.
- Right angle.
- Obtuse angle.
- Straight angle.
- Reflex angle.

Similarly, what are angles called? In plane geometry, an **angle** is the figure formed by two rays, **called** the sides of the **angle**, sharing a common endpoint, **called** the vertex of the **angle**. **Angles** formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane.

People also ask, how many types of angles are there?

**In geometry, there are three types of angles:**

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

What is a reflex angle?

**Reflex angles** are **angles** measuring greater than 180 degrees and less than 360 degrees. The measure of a **reflex angle** is added to an acute or obtuse **angle** to make a full 360 degree circle.
