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