Angles - Foundation
For your exam, you will need to know the following types of angle:
Any angle that is less than 90° is called an acute angle.
Any angle which is between 90° and 180° is called an obtuse angle.
Any angle that is between 180° and 360° is called a reflex angle.
You also need to remember that the angles in a triangle add up to 180°, and that the angles in a quadrilateral add up to 360°.
p + q + r = 180° w + x + y + Z = 360°
