ANGLES<br />
G<br />
Geometry<br />
Angles can be found everywhere, especially right angles, which<br />
are the most common. When a horizontal and vertical line join<br />
(perpendicular lines) they form a right angle at the corner.<br />
1. Find and draw three right angles in the classroom.<br />
(a) (b) (c)<br />
A right angle is 90°. A straight angle (two right angles) is 180°.<br />
Half a right angle is 45°.<br />
2. Trace over the right angles in red. Trace the straight line angles in<br />
yellow and the half-right angles in blue.<br />
