Name: Shannon Who: Student Level: Secondary If given an isosceles triangle...with <A=100 <B=40 <C=40, find the measurements of the sides of the triangle. Is there any possible way to do this, without knowing a side, if so, please explain in detail. 

Hi Shannon, NO. You are given only the shape of the triangle. If you wish, you can find the ratios of the sides using your calculator. For example if you let the base be 2a units, and the other sides each be x units, then a/x is cos (40^{o}). Chris
