PTS: 6 REF: 061038ge STA: G.G.39 TOP: Special Parallelograms 595 ANS: Quadrilateral ABCD, AD ≅ BC and ∠DAE ≅ ∠BCE are given. AD  BC because if two lines are cut by a transversal so that a pair of alternate interior angles are congruent, the lines are parallel. ABCD is a parallelogram because if one pair of opposite sides of a quadrilateral are both congruent and parallel, the quadrilateral is a parallelogram. AE ≅ CE because the diagonals of a parallelogram bisect each other. ∠FEA ≅ ∠GEC as vertical angles. AEF ≅ CEG by ASA. PTS: 6

Because AB  DC , AD ≅ BC since parallel chords intersect congruent arcs. ∠BDC ≅ ∠ACD because inscribed angles that intercept congruent arcs are congruent. AD ≅ BC since congruent chords intersect congruent arcs. ∠DAC ≅ ∠DBC because inscribed angles that intercept the same arc are congruent. Therefore, ACD ≅ BDC because of AAS. PTS: 6 599 ANS:

AB  CD and AD  CB because their slopes are equal. ABCD is a parallelogram

because opposite side are parallel. AB ≠ BC . ABCD is not a rhombus because all sides are not equal. AB ∼ ⊥ BC because their slopes are not opposite reciprocals. ABCD is not a rectangle because ∠ABC is not a right angle. PTS: 4

ID: A 600 ANS: Rectangle ABCD with points E and F on side AB , segments CE and DF intersect at G, and ∠ADG ≅ ∠BCE are given. AD ≅ BC because opposite sides of a rectangle are congruent. ∠A and ∠B are right angles and congruent because all angles of a rectangle are right and congruent. ADF ≅ BCE by ASA. AF ≅ BE per CPCTC. EF ≅ FE under the Reflexive Property. AF − EF ≅ BE − FE using the Subtraction Property of Segments. AE ≅ BF because of the Definition of Segments.

OA ⊥ PA and OB ⊥ PB because tangents to a circle are perpendicular to a radius at a point on a circle. ∠PAO and ∠PBO are right angles because of the definition of perpendicular. ∠PAO ≅ ∠PBO because all right angles are congruent. AOP ≅ BOP because of HL. ∠AOP ≅ ∠BOP because of CPCTC.

The length of each side of quadrilateral is 5. Since each side is congruent, quadrilateral MATH is a rhombus. The slope of MH is 0 and the slope of HT is − 4 . Since the slopes are not negative 3 reciprocals, the sides are not perpendicular and do not form rights angles. Since adjacent sides are not perpendicular, quadrilateral MATH is not a square. PTS: 6
