Six Types of Angles
In this lesson students will learn how to identify different types of angles.
3
4
Right Angle
An angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
5
Acute Angle
An acute angle is an angle that measures between 90° and 0°, meaning it is smaller than a right angle (an “L” shape) but has at least some space between the two lines that form it.
6
Obtuse Angle
In Geometry, an obtuse angle is an angle that is greater than 90° and less than 180°
7
Straight Angle
A straight angle always forms a straight line. The value of the straight angle is 180°.
8
Reflex Angles
A reflex angle is the larger angle, it’s always more than 180° (half a circle) but less than 360° (A full circle). It’s possibly the most confusing of the angles because it’s always on the outside.
9
Full Angle
A Full Angle is an angle that has a measure of exactly 360°. I looks like a circle.
