Students may also make use of area formulas that they have previously derived, like A=bh/2 for triangles or A = bh for parallelograms. (1) The figure below shows polygon c, kite HGJI. Right triangle HGM is relocated to right triangle GJO, and right triangle MIH is relocated to right triangle NJI. These will be expanded to find the area of trapezoids, kites and rhombi. Discuss questions from lesson 1’s Ticket Out the Door. Presentation of New Information or Modeling: New vocabulary—height of a trapezoid, diagonal of a rhombus/kite, trapezoid, rhombus, kite. New formulas—area of trapezoid, area of kite, area of rhombus.

Lesson Objectives: In this lesson, we will be learning the formula for the area of a trapezoid, as well as learning how to find the areas of rhombuses and kites.. You should be able to do the following: Find the area of a trapezoid Given the diagonal lengths of a rhombus or kite, find its area Warm-Up: Find the area of the parallelogram below. 600 The PowerPoint PPT presentation: "6'7 Areas of Triangles and Quadrilaterals" is the property of its rightful owner.
