On a coordinate grid, graph these points to create a triangle:

What kind of triangle is it?

Look at the angles of the triangle.

Where could you add a fourth point so that when the points are connected you will make a rectangle?

Plot point

*D*onto the coordinate grid so that points,,, andform a rectangle.What point can you add to create a trapezoid?

Answers will vary. Plot point

to make a possible trapezoid.Translate the original triangle

units to the left and units down. Label the coordinates of the vertices of the new triangle. Move points

,, andunits to the left and units down.
