B C

Imagine, AC is the pole. BC is its shadow on the ground. If angle of elevation = 45°, then , angle B = 45°. Also, we know, angle C = 90°. So, angle A = 45° ( by angle sum property ).

So, ∆ABC is an isosceles triangle with two angles equal to 45°. So, sides opposite to those angles will also be equal in measure. That is, BC = AC. So, Shadow of pole = Length of pole.

Hope this helps!!!!
