1 Write ‘greater than’, ‘less than’ or ‘equal to’ 90° for each of these angles. (a) (b) (c) (d)
2 Solve this problem. Letisha draws some 2-D shapes. She counts six angles that are equal to 90°, five angles that are less than 90° and five angles that are greater than 90°. Which shapes could they be? Sketch your solution on grid paper. Can you find more than one possibility? 3 Follow the instructions. Which four shapes does Leon collect? (a) Leon turns 90° left. (b) He then makes a turn to his right that is greater than 90° but not as much as a half turn. (c) Leon now makes a quarter of a turn right. (d) Finally Leon makes a turn to his left that is less than 90°. What instructions can you give Leon to collect the rest of the shapes?
