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.
ADDENDUM (a) is the height by which a tooth projects beyond the pitch circle or pitch line. BASE DIAMETER (Db) is the diameter of the base cylinder from which the involute portion of a tooth profile is generated. BACKLASH (B) is the amount by which the width of a tooth space exceeds the thickness of the engaging tooth on the pitch circles. As actually indicated by measuring devices, backlash may be determined variously in the transverse, normal, or axial-planes, and either in the direction of the pitch circles or on the line of action.
