Graph and connect the points

*G*(−2, 2),*H*(3, 2),*I*(6, 6), and*J*(1, 6) to form*GHIJ*. 7-32 HW eTool (Desmos).Homework Help ✎What specific type of shape is quadrilateral

*GHIJ*?**Justify**your conclusion.Find the equations of the diagonals

and . Compare the slopes of the diagonals. How do the diagonals of a rhombus appear to be related?

Find

*J′*if quadrilateral*GHIJ*is rotated 90° clockwise () about the origin. Find the area of quadrilateral

*GHIJ*.

Use the Pythagorean Theorem and the triangles shown to determine the lengths of *GJ* and *HI*.

This will help you determine the type of shape.

What type of quadrilateral (other than a square) has sides all of the same length?

Use slope triangles to find the equations for the diagonals.

If one line has a slope that is the opposite of the reciprocal of the slope of another line, the two lines are perpendicular.

Area of a parallelogram = (*b*)(*h*).

Move the points in the eTool to their given coordinates. The shape will appear when all the points are in their proper places.
