Lengths in Polygons on the Plane

Graph the triangle that has vertices at $\left(2,-2.5\right)$(2,−2.5), $\left(-2.5,0\right)$(−2.5,0) and $\left(-2.5,-2.5\right)$(−2.5,−2.5).

Graph the polygon that has vertices at $\left(-4.5,-4\right)$(−4.5,−4), $\left(3,1.5\right)$(3,1.5), $\left(4,-3.5\right)$(4,−3.5) and $\left(-3.5,1\right)$(−3.5,1).

A quadrilateral has vertices at $\left(-3.5,-2\right)$(−3.5,−2), $\left(2.5,-2\right)$(2.5,−2), $\left(-3.5,4\right)$(−3.5,4) and $\left(2.5,4\right)$(2.5,4).
