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
, , , and form 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.
