1. What shape do you think this is? The corners have coordinates: P (-5, -5), Q (-30, 10), R (-5, 25), S (20, 10) Rectangle RhombusSquare Trapezoid Just guess!

2. A triangle has vertices at A(-1, -1), B(2, 0) and C(1, 3). What type of triangle is it? Justify your decision. Right Isosceles Equilateral Scalene

3. A (-1, -1) C (1, 3) B (2, 0)

6. To solve a problem that involves a geometric figure, it is a good idea to start by drawing a diagram of the situation on a coordinate grid Parallel lines have the same slope Perpendicular lines have slopes that are negative reciprocals
