Angle proofs worksheet with answers
Statement #5: In this step, the “Angle Addition” postulate is applied to make one angle, ∠EAC, since the two non-overlapping angles share ray AD. Statement #6: Since the measurement of angle BAD equals the sums of the measures of angles EAD and CAD, and this sum is equal to the measure of angleInterior Angles of Polygon Worksheet Exterior Angles of a Polygon; P roving Triangles Congruent .

DOUBLE-ANGLE FORMULAS. The double-angle formulas are summarized as follows: sin(2θ) = 2sinθcosθ cos(2θ) = cos2θ − sin2θ = 1 − 2sin2θ = 2cos2θ − 1 tan(2θ) = 2tanθ 1 − tan2θ.
