**Ms. Sue**, Tuesday, February 1, 2011 at 11:38amDraw a straight line from the mid point of one side to the opposite vertex.

Use the Pythagorean Theorem to find the length of this line. Let b = this line (the height).

a^2 + b^2 = c^2

3^2 + b^2 = 6^2

9 + b^2 = 36

b^2 = 27

b = 5.2

Now use this formula to find the area of this triangle.

A = 1/2bh
