A friend of mine asked me to find the area, perimeter and the measure of each side of the triangle in the picture, but I can't, so I would like someone to solve it and explain how you did it. triangle.jpg |

Here's a diagram for the case where the height is 18 and the triangle is assumed to be isosceles. It should give you some ideas. Isosceles.PNG |
