Investigate how to find the area of a triangle.

Investigation:[br]1) Move point D so that the triangle is a right triangle, then describe what happens as you move the Hint slider.[br]2) Move point D to make a.) an obtuse triangle, and b.) an acute triangle. For each triangle, move the Hint slider, then describe what changes as well as your end result.[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.
