The measure of a base angle of an isosceles triangle whose vertex angle measures 72 is 54 degrees.
Given that,
Based on the above information, the calculation is as follows:
= 180 - 72
= 108 degrees
For each base angle it is 54 degrees.
Therefore we can conclude that the measure of a base angle of an isosceles triangle whose vertex angle measures 72 is 54 degrees.
