  1. Kites in Geometry www.assignmentpoint.com

  2. Lesson Plan – Parallelograms, Kites, Trapeziums. www.assignmentpoint.com

  3. Starter Activity Complete the table provided by drawing a picture of each polygon and writing in the formula for finding the area. www.assignmentpoint.com

  4. Today we are learning I am starting the lesson on level _____________________ By the end of this lesson I want to be able to _____________________ www.assignmentpoint.com

  9. 4cm 5cm So area of a parallelogram is ; Base x perpendicular height = 20cm2 www.assignmentpoint.com

  10. 3cm Height hasn’t changed – still 8cm 8cm 8cm Width has halved to 3cm. 6cm So – area of a kite or rhombus is; Half of base x height = 3 x 8 = 24cm2 www.assignmentpoint.com

  11. Now for the tricky one; 6cm 1cm 1cm 4cm 1cm 1cm 10cm www.assignmentpoint.com

  12. Now for the tricky one; 6cm 4cm 10cm The width of the rectangle is the same as the height of the trapezium. The length of the rectangle is the same as the bottom and top of the trapezium added together and then halved. So – area of a Trapezium is; Half the sum of the parallel sides x the gap between them. = (6+10)/2 x 4 = 32cm2 www.assignmentpoint.com

  13. Today’s Task • Work out the area of each polygon, you will need to measure the sides. • Fit them together to create a house • Find the total area of the house. www.assignmentpoint.com
