More About Base Angle Theorem. 1  Base angles of an isosceles triangle are equal.  Converse of the base angle theorem is also true, i.e. if two angles of a triangle are congruent, the sides opposite to these angles are congruent.
A right angle is an angle with measure equal to 90 degrees. An acute angle is an angle with a measure between 0 and 90 degrees. An obtuse angle is an angle with a measure between 90 and 180 degrees. Two angles are complementary if the sum of their measures is equal to 90 degrees.
