Quadrilaterals

15. Use the Shape Sort Cards: Quadrilaterals pages in the Student Activity Book to make shapes with ordered pairs.

16. Cut apart the cards from the Sort Cards: Quadrilaterals pages. Sort the quadrilaterals into two groups: shapes with right angles and shapes without right angles.
1. Which quadrilaterals have at least one right angle?
2. Which quadrilaterals do not have right angles?
3. What do you notice about the coordinates of the shapes that have right angles?
17. Draw a different quadrilateral on one of the cards on the Blank Sort Cards pages in the Student Activity Book. List the coordinates and label the vertices.
18. Look at the shapes that have right angles. Sort these shapes into 2 piles. What property did you use to sort the shapes?
19. Look at the shapes that do not have right angles. Sort these shapes into 2 piles. What property did you use to sort the shapes?
20. Plot each shape on one of the cards on the Blank Sort Cards pages. What are the properties of each shape?
1. (2, 2), (11, 0), (19, 6), (8, 10)
2. (2, 5), (4, 2), (19, 6), (4, 8)
