On graph paper draw a coordinate grid with $x$- and $y$-axes. Graph shapes A, B, and C as described below.

1. Shape A is a triangle with vertices $(1, 1),$ $(3, 3),$ and $(2, 4)$.

2. Shape B is a square with vertices $(2, -1),$ $(4, -1),$ $(2, -3),$ and $(4,-3)$.

3. Shape C is a rectangle with vertices $(-3, 1),$ $(-3, 4),$ $(-1, 4),$ and $(-1, 1)$.
