Find a Missing Angle of a Polygon using Similarity
Question
The two pentagons in the figure below are similar. If angle alpha corresponds to the angle labeled on pentagon B, what is (m)/(_(alpha )) ?
Solution
Since the polygons are similar, the corresponding angles are equal. Therefore,
(m)/(_(alpha ))=108deg .
