This geometry video tutorial explains how to find the area of a triangle using multiple formulas. It explains how to find the area of a right triangle using the formula A=1/2bh. All you need is the base and the height of the triangle. This video contains an example of using the pythagorean theorem to find the missing side of a right triangle. In addition, this tutorial provides the formula to find the area of an equilateral triangle given all 3 sides. This lesson also provides the formula to find the area of a scalene triangle given SAS - two sides and an angle using sines / trigonometry. Finally, this video explains how to find the area of a triangle with all 3 sides (SSS) using heron's formula. As you can see, this video contains plenty of examples and practice problems.
