Question

In isosceles triangle ABC, points D and F are on leg CB while point E is on leg AB so that AC=AD=DE=EF=BF. Find the measures of the angles of triangle ABC.

Answer 1

Answer: 60 degrees

Explanation:

∠C = 2x = 2 * 30 = 60 degrees.

∠CAB = 2∠CAD = 2 * 30 = 60 degrees.

∠ABC = 2∠EFB = 2 * 30 = 60 degrees.
