Example 8. In an isosceles triangle, the base angles areequal. The vertex angle is twice either base angle. Whatare the angles of the triangles?

Answer»

Let equal angles of isosceles triangle be xThen vertex angle is 2x

Using triangle sum propertyx + x + 2x = 1804x = 180x = 45

Angles are 45, 45 and 90
