PDF-QUADRILATERALS

C You have studied many properties of a triangle in Chapters 6 and 7 and you know thaton joining three noncollinear points in pairs the figure so obtained is a triangle Nowlet us mark four points. The parallel sides are parallel by definition 2 The opposite sides are congruent 3 The opposite angles are congruent 4 The diagonals bisect each other 5 Any pair of consecutive angles are supplementary Properties of Rectangles In a rectangle 1 All t 4 sides. 2. angles add to 360. Parallelogram. Opposite sides are parallel and congruent. Opposite angles are congruent. Adjacent angles are supplementary. Diagonals bisect . eachother. Rectangle. Opposite sides are parallel and congruent. Sara . Beberman. Olivia . DeFlumeri. Olivia Huynh. Amanda . Okaka. Parallelogram. A parallelogram is a quadrilateral with both pairs of opposite sides parallel. - if a quadrilateral has two pairs of opposite sides congruent then it is a parallelogram ex: (AB. for . Sem. 1 Quiz 5.

This Slideshow was developed to accompany the textbook. Larson Geometry. By Larson. , R., Boswell, L., . Kanold. , T. D., & Stiff, L. . 2011 . Holt . McDougal. Some examples and diagrams are taken from the textbook.. True/False. Every square is a rhombus.. TRUE – four congruent sides. True/False . If the diagonals of a quadrilateral are perpendicular, then it is a rhombus.. False – diagonals don’t have to be congruent or bisect each other..
