Geometry 8.2 – Use Properties of Parallelograms Learning Target: By the end of today’s lesson we will be able to successfully find angle and side measures in parallelograms. If a quadrilateral is a parallelogram, then its opposite sides are congruent. If PQRS is a parallelogram, then _______ RS and QR ________ If a quadrilateral is a parallelogram, then its opposite angles are congruent. If PQRS is a parallelogram, then P ________ and ________ S. If a quadrilateral is a parallelogram, then its consecutive angles are supplementary. If PQRS is a parallelogram, then x° + y° = ________ 1) Find the values of each variable. a) b) 2) As shown, a gate contains several parallelograms. Find mADC when mDAB = 65°. If a quadrilateral is a parallelogram, then its diagonals bisect each other. QM ________ and PM __________ 3) The diagonals of parallelogram VWXY intersect at point Z. Find the coordinates of Z. 4) Given that FGHJ is a parallelogram, find MH and FH. PROPERTIES OF A PARALLELOGRAM: - Opposite sides are congruent - Opposite angles are congruent - Consecutive angles are supplementary - Diagonals bisect each other
