Remember that angles are formed when two edges/lines meet. An angle gives idea of measure of turn. Hence, to measure the angle of an object /lines, we measure the amount of turn from one position to another. The following are types of angles:
Right angle, Acute angle, Obtuse angle and Reflex Angle.
Straight Line = 180
Right angle =90
Acute angles are less than 90
Obtuse angles are greater than 90
Reflex angles are greater than 180 but less than 360
Home – work: Draw a shape that contains at least one acute angle and one obtuse angle.
Draw a shape that contains at least one right angle and one acute angle.
