​What is an ANGLE?

​ Angles are the space (usually measured in degrees between two intersecting lines or surfaces at or close to the point where they meet. We have six type of angles. Their names are right angle, straight line, obtuse angle, reflex angle, acute angle.

​Right Angle.

​A right angle is an angle that measures exactly 90 degrees with a square vertex/arc.

​Straight Angle.

​A straight angle is an angle that measures exactly 180 degrees with a curved vertex/arc.

​Straight Angle.

​A straight angle is an angle that measures exactly 180 degrees with a curved vertex/arc.

​Obtuse Angle.

​An obtuse angle is any angle that measures greater than 90 degrees, but less 180 degrees and has a curved vertex/arc

​Reflex Angle.

​A reflex angle is an angle greater than 180 degrees and less than 360 degrees and have an curved vertex/arc on the outside.

​Acute Angle

​An acute angle measures less than 90 degrees and has a curved vertex/arc inside.
