Deriving formula for area of a kite


 * Estimated Time : 30 minutes.
 * Materials/ Resources needed: Laptop, geogebra file, projector and a pointer.
 * Prerequisites/Instructions, if any
 * 1) Basics of a triangle and kite should have been done.
 * Multimedia resources: Laptop
 * Website interactives/ links/ / Geogebra Applets
 * Process:
 * 1) The teacher can project the geogebra file on kite.
 * 2) Show them that a kite is made of two isosceles traingles.
 * 3) Sum of areas of these two triangles would be the area of the kite.
 * Developmental Questions
 * 1) What is a kite ?
 * 2) What are the properties of a kite.
 * 3) What other figures can you see in a kite ?
 * 4) What types of triangles are these ?
 * 5) Identify the two isosceles triangles ?
 * 6) What is the formula to find the area of a triangle ?
 * Evaluation:
 * 1) Choosing which two traingles out of the 8 visible types would be easy to deduce the area of kite ?
 * Question Corner:
 * 1) Recall the two formulae that you know to find the area of a triangle.
