Angles

We will learn to recognize and name right angles, tapered angles and right angles in the shapes of rectangles, equal squares and triangles.

ANGLES
An angle is a shape formed by two lines that share the same endpoint, called the vertex of an angle. Angles provide a way to express the difference in gradient between two lines that meet at an angle without having to define the gradient of both.

Angles can be divided into 3 types which are right angle, acute angle and obtuse angle.

RIGHT ANGLE

The right angle is at 90°.

ACUTE ANGLE

An acute angle is an angle whose value is less than 90°.

OBTUSE ANGLE

An obtuse angle is greater than 90° but less than 180°.
