**ANGLES
GEOMETRY**

Angle is a measure
of rotation. Angles are formed when two or more lines
meet or intersect. There are different types of angles
depending on their sizes. The basic types of angles
and their diagrams include:

**1. Acute Angles**

These are the angles that between 0 and 90 degrees
i.e greater than 0 but less than 90 degrees.

It is diagrammatical represented thus:

2. Right Angle

This is an angle that is 90 degrees

It is diagrammatical represented thus:

3. Obtuse Angles

These are the angles that between 90 and 180 degrees
i.e greater than 90 but less than 180 degrees.

It is diagrammatical represented thus:

**4. Reflex Angles**

These are the angles that between 180 and 360 degrees
i.e greater than 180 but less than 360 degrees.

It is diagrammatical represented thus:

**PLANE GEOMETRY
FACTS**

In solving plane geometry
problems in mathematics, there are some facts that
we must know. These facts are highlighted below:

**1. ANGLES
AT A POINTS ARE EQUAL TO 360 DEGREES**

The sum of all the
angles that make up a point is 360 degrees.
