Show ONE PAIR of opposite sides are congruent and parallel (same slope and distance). Both of these facts allow us to prove that the figure is indeed a parallelogram. WZ ≅ XY by the given. Quadrilateral RSTU has one pair of opposite parallel sides and one pair of opposite congruent sides as shown. Yes, one pair of opposite sides could measure 10 in., and the other pair could measure 8 in. ∠ZWY ≅ ∠XYW by the alternate interior ∠s theorem. WY ≅ WY by the reflexive property. 6-3 practice proving that a quadrilateral is a parallelogram are congruent. By the reflexive property, MO ≅ MO. In the video below: - We will use the properties of parallelograms to determine if we have enough information to prove a given quadrilateral is a parallelogram. 3 Select Apache Tomcat 7011 for server and Java EE 5 for J2EE Version Click. In your My Sheets folder create a new spreadsheet and rename it Lesson 44 2. To prove quadrilateral WXYZ is a parallelogram, Travis begins by proving △WZY ≅ △YXW by using the SAS congruency theorem.
Another approach might involve showing that the opposite angles of a quadrilateral are congruent or that the consecutive angles of a quadrilateral are supplementary. Nsecutive interior angles are supplementary. This preview shows page 1 out of 1 page. Prove: MNOL is a parallelogram. If two lines are cut by a transversal and alternate interior angles are congruent, then those lines are parallel. 6-3 practice proving that a quadrilateral is a parallelogram lisbdnet. Show BOTH PAIRS of opposite angles are congruent 4. Let's set the two angles equal to one another: $m \angle BAC = m \angle DCA$ Plug in our knowns from the diagram: $2x + 15 = 4x - 33$ Subtract $15$ from each side of the equation to move constants to the right side of the equation: $2x = 4x - 48$ Subtract $4x$ from each side of the equation to move the variable to the left side of the equation: $-2x = -48$ Divide both sides of the equation by $-2$ to solve for $x$: $x = 24$.

Course Hero uses AI to attempt to automatically extract content from documents to surface to you and others so you can study better, e. g., in search results, to enrich docs, and more. Upload your study docs or become a. If so, then the figure is a parallelogram. Check all that apply. Proving a Quadrilateral Is a Parallelogram - Assignment Flashcards. ∠ZWY ≅ ∠XWY by the corresponding ∠s theorem. This means we are looking for whether or not both pairs of opposite sides of a quadrilateral are congruent. Well, we must show one of the six basic properties of parallelograms to be true! C. It is not a parallelogram because the parallel sides cannot be congruent. A tip from Math Bits says, if we can show that one set of opposite sides are both parallel and congruent, which in turn indicates that the polygon is a parallelogram, this will save time when working a proof. Other sets by this creator.
Write several two-column proofs (step-by-step). PRACTICE: (4) One pair of opposite sides are parallel and congruent (2) Both pairs of opposite sides are congruent (3) Both pairs of opposite angles are congruent. Finally, you'll learn how to complete the associated 2 column-proofs. 518: 3-11, 13-15, 23-31. Based on the converse of the alternate interior angles theorem, MN ∥ LO and LM ∥ NO.
