Math; Questions With All Correct
Answer
Given: Parallelogram HIJK with diagonals intersecting at L
Prove: / Correct answer-2) Opposite sides in a parallelogram are congruent
3) Diagonals of a parallelogram bisect each other
4) SSS
5) CPCTC
The diagonals of parallelogram DEFG intersect at H. What congruence statements can you make about
the parallelogram? Correct answer-HE = HG, HD = HF, ED = FG, EF = DG, angle GDE = angle EFG, and
angle DEF = FGD. There are countless others, such as certain angles totaling 180 degrees.
Explain how certain values of x and y make ABCD a parallelogram. Correct answer-In order for ABCD
to be a parallelogram, the diagonals must bisect each other. If segment AC bisects segment BD, then 4y -
5 = 2y + 1. Solving this equation, we get that y = 3. If segment BD bisects segment AC, then 4x = x + 3, so
x = 1. Therefore, if x = 1 and y = 3, then ABCD is a parallelogram.
Quadrilateral ABCD has side lengths of AB = 13w - 5, BC = 5z - 2, CD = 13w - 5, and AD = 3z + 5. Find the
value of z for which quadrilateral ABCD is a parallelogram. Correct answer-7/2
In quadrilateral HELP, /. What other condition would prove that HELP is a parallelogram? Correct
answer-HE = LP
Describe a method for verifying that quadrilateral EFGH is a parallelogram if only the interior angle
measures of EFGH are known. Explain your answer. Correct answer-By the converse of the
parallelogram angle theorem, if both pairs of opposite angles are congruent, then quadrilateral EFGH is
a parallelogram.
Which of the following is not always true? Correct answer-In a rhombus, the diagonals are
perpendicular.
The diagonals of rhombus WXYZ intersect at point P. If WP = 4 and ZP = 3, find the perimeter of the
rhom Correct answer-20.
ABCD is an isosceles trapezoid. If AD = BC, B= x+10 and C= 2x-30, find the measure of angle D Correct
answer-130 degrees.
Which statement about kite PQRS must be true? Correct answer-RP is perpendicular to QS.
Given: Isosceles trapezoid ABCD with AB=CD
Prove: A and C are supplementary. Correct answer-Statement : Reason
1. Isosceles trapezoid ABCD : Given

Given: Parallelogram HIJK with diagonals intersecting at L Prove: / Correct answer-2) Opposite sides in a parallelogram are congruent

  1. Diagonals of a parallelogram bisect each other
  2. SSS
  3. CPCTC The diagonals of parallelogram DEFG intersect at H. What congruence statements can you make about the parallelogram? Correct answer-HE = HG, HD = HF, ED = FG, EF = DG, angle GDE = angle EFG, and angle DEF = FGD. There are countless others, such as certain angles totaling 180 degrees. Explain how certain values of x and y make ABCD a parallelogram. Correct answer-In order for ABCD to be a parallelogram, the diagonals must bisect each other. If segment AC bisects segment BD, then 4y - 5 = 2y + 1. Solving this equation, we get that y = 3. If segment BD bisects segment AC, then 4x = x + 3, so x = 1. Therefore, if x = 1 and y = 3, then ABCD is a parallelogram. Quadrilateral ABCD has side lengths of AB = 13w - 5, BC = 5z - 2, CD = 13w - 5, and AD = 3z + 5. Find the value of z for which quadrilateral ABCD is a parallelogram. Correct answer-7/ In quadrilateral HELP, /. What other condition would prove that HELP is a parallelogram?
