PERCENTAGES

Percent % means out of 100.A way of writing a fraction with a denominator of 100.

FINDING % OF A NUMBER

METHOD 1 - FIND 1% Divide by 100.

TYPES OF ANGLES

MEASURING ANGLES

1. Place the centre point of the protractor on the vertex of the angle.2. Line up the base line (0 line) of the protractor with one of the angle rays.3. To find the angle, always read from 0, look at the number the second ray crosses.

angle = 35°

ACUTE ANGLEless than 90°

OBTUSE ANGLEmore than 90°less than 180°

REFLEX ANGLEmore than 180°less than 360°
