Congruent Supplements Theorem: Iftwo angles are supplements of the same angle (or of congruent angles), then thetwo angles are congruent.

    Using the definition of supplementary angles, m∠1 + m∠2 = 180 and m∠2 + m∠3 = 180.Applying the substitution property of equality, m∠1 + m∠2 = m∠2 + m∠3. The AdditionProperty of Equality allows us to subtract m∠2 from each side of the equation. Therefore,m∠1 = m∠3 and ∠1 ∼= ∠3.2. What are some things you cannot assume when looking at a diagram?

    10. Assume ABCD has four obtuse angles. Then by the Polygonal Sum Theorem, >180 + > 180 + > 180 + > 180 = 360. However, the left side has a sum greater than360 degrees. Therefore, ABCD cannot have four obtuse angles.

    11. Assume an obtuse triangle has a right angle. Then by the Triangle Sum Theorem,90 + x + y = 180. Using the Addition Property of Equality, x + y = 90. However, theAddition to Inequality Property states that x < 90 and y < 90. This means that no anglesare obtuse. Therefore, an obtuse triangle cannot have a right angle.

  • Answers: Parallelograms

    1. Because ABCD is a parallelogram, its opposite sides are parallel and congruent. There-fore, AB ∼= DC. Diagonals in a parallelogram bisect each other, so AE ∼= CE andBE ∼= DE. By The SSS Triangle Congruence Postulate, △AEB ∼= △DEC. And bythe CPCT, ∠AEB ∼= ∠DEC.2. Opposite angles in a parallelogram are congruent and consecutive angles are supplemen-tary.

    3. 77.14◦ and 102.86◦

    4. MAPS is not a parallelogram. The order of the variables means A and P are consecutivevertices. These two angles are equal not supplementary.

    5. By showing: the diagonals bisect each other, an opposite pair of segments are paralleland congruent, both pairs of opposite segments are parallel, both pairs of opposite segmentsare congruent, both pairs of opposite angles are congruent.

    6. By the reflexive postulate, segment AC is congruent to segment AC. By the SAScongruence theorem, △DAC ∼= △BCA. Using the CPCT , AB ∼= DC. Therefore, bothpairs of opposite sides are congruent and ABCD is a parallelogram.
