On graph paper, draw a coordinate graph 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 $\left(4, −3\right)$.

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