Area of a Triangle

Investigate how to find the area of a triangle.
Investigation: 1) Move point D so that the triangle is a right triangle, then describe what happens as you move the Hint slider. 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. 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.
