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.
The degree measure of a minor arc of a circle is the measure of. its corresponding central angle. In Figure 19.2, Degree measure of PQR = xÂ°. The degree measure of a semicircle in 180Â° and that of a major. arc is 360Â° minus the degree measure of the corresponding minor. arc. Relationship between length of an arc and its degree measure. Length of an arc = circumference. degree measure of the arc. 360. Ã.
