• If the two lines cut by a transversal are parallel, then these special pairs of angles are congruent: alternate interior angles, alternate exterior angles, and corresponding angles. 64°; Sample answer: ∠3 and ∠8 are corresponding angles. So, m∠8 = 64°. 64°; Sample answer: ∠3 and ∠10 are alternate interior angles. So, m∠10 = 64°.[PDF]

answer: The pairs of base angles of a trapezoid inscribed in a circle must be congruent. Draw any inscribed angle. Use the compass to copy the arc that this angle intercepts. Mark off the same arc from the vertex of the inscribed angle. Connect the points. 6. cannot be inscribed in a circle Reteach 1. m∠LMP = 18°; mMNq = 96°[PDF]
