In this worksheet you will investigate how to find the area of a triangle.

Investigation:[br][br]1) Move point D so that the triangle is a right triangle, then move the Hint slider, describe the end result. [br][br]2) Move point D to make an obtuse triangle and move the Hint slider, describe the end result. (perform this task for an acute triangle as well)[br][br]3) What conjecture can you make about the formula for area of a triangle? Test this conjecture with 5 different base and height combinations and record your results.

Find the area of the displayed triangle. Change the triangle to find different areas.
