Question

Using the vertices: B(-9,1), E(2,3), F(12, -2), G(1,-4). Determine whether BEFG is a rhombus, a
rectangle, or a square. List all that apply and show the steps

Answer 1

Have you considered plotting the points and take a look?

Answer 2

if not, you can always check the side lengths. If they are all equal, then you need to check for right angles, using the Pythagorean theorems. If a diagonal qualifies as an hypotenuse, then you have a square, not just a rhombus.
