PPT- Area of Quadrilaterals

SECTION 502 After completing this lesson you will be able to say I can use composition and decomposition to determine the area of quadrilaterals I can solve problems involving area of quadrilaterals using composition and decomposition. Is it true or false?. If an animal is a panda, then it is black and white.. If an animal is not a panda, then it is not black and white.. (False—zebra). Which angle is the smallest? Which side is the shortest?. 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. entry area tel|mobile [0-9]+ [0-9]+ fwd free entry entry entry area tel mobile area tel mobile 03 10091729 1201 1222 free 1887 free fwd entry tel|mobile entry [0-9]+ area [0-9]+ tel|mobile [0-9]+ [0-9 Mackenzie Simonsen. Polygons. Triangle- A plane figure with three straight sides and three angles. A way to remember a triangle is that . tri- . means three and a . tri. angle has three sides. . Quadrilateral- A plane figure with 4 straight sides and 4 angles. A way to remember is that . “…geometric shapes are the alphabet in which the book of nature is written." -Galileo. You are learning to classify quadrilaterals.. Objectives. Point. -. A place in time or space. Line. - . a series of points that extends forever. Is it possible to trace the following figure without retracing any lines and without lifting your pencil from the paper? If yes, trace the route. If not, explain why it is not possible. Solve for x . What is a quadrilateral?. . A quadrilateral is a closed 2 dimensional figure with that are line segments. . . four sides. What is a parallelogram?. Quadrilateral – 4 sides. Properties of Quadrilaterals. Due on. . Unscramble these anagrams:. tiek. qruesa. surobhm. malgorallprae. What is the name of this shape?. Parallel. ogram has two pairs of . parallel. sides.. Trapezium has exactly one pair of parallel sides. Looks like a trapeze wire.. What is a polygon?. Closed figure. At least 3 sides. Line segments are sides. Sides meet is call a vertex. More Polygon Terms. Diagonal – connects two non consecutive vertices. Concave – at least one diagonal outside polygon, dented in. A Parade of Four-Sided Polygons. Quadrilaterals. There are many different types of quadrilaterals. We identify quadrilaterals using their sides and angles. . Side. Angle. Let’s Review…. All polygons are made up of line segments and angles. The line segments that create quadrilaterals will be parallel, perpendicular, OR intersecting.. quadrilateral. trapezoid. parallelogram. rectangle. rhombus. square. What is this?. trapezoid. (and quadrilateral). What is this?. parallelogram. Recognize and apply the properties of rhombi and squares.. Determine whether quadrilaterals are rectangles, rhombi, or squares.. Properties of a rhombus. A rhombus is a parallelogram with all four sides congruent.. Hidden Area . Johari Window. Course Objective. Describe the History of Johari Window.
