If AB = BC, triangle ABC is isosceles,
with congruent angles at A and C,
meaning that those angles have the same measure.
If the measures of those angles, in degrees, are and .
then .

Solving that equation:

.

So the measure of angle A, in degrees, is
.
Angle A measures .
Angle C has the same measure,
and angle B measures
.
