Question from ginny, a student: If a equilateral triangle has side lengths of 41.33m how would i calculate the area? |
Ginny,
In my diagram P is the midpoint of BC.
Triangles APC and ABP are congruent. Can you see why? This means that angle APC is a right angle and hence you can use the Theorem of Pythagoras to find |AP| which is the height of the triangle.
