| + | *Estimated Time : 20 minutes. |
| + | *Materials/ Resources needed: Laptop, geogebra file, projector and a pointer. |
| + | *Prerequisites/Instructions, if any: |
| + | #Students should have prior knowledge about a kite and its properties. |
| + | #They should know a perpendicular line and its construction. |
| + | #They should know to construct a line segment of given length by constructing arcs. |
| + | *Multimedia resources: Laptop |
| + | *Website interactives/ links/ / Geogebra Applets: This geogebra file has been done by ITfC-Edu-Team |

| + | *Process: |
| + | #The teacher can initially have a recaptualation of the concept of a kite and its properties. |
| + | #Give them measures say, "Construct a kite which has its congruent sides as 4 cm and 6 cm a pair with one of its diagnols measuring 5cm. |
| + | #Can project the geogebra file and explain the steps of construction for the given measures. |
| + | *Draw a rough small kite labelling with the given measures. |
| + | *Begin with drawing a line segment, the diagnol of a given measure, here 5 cm. label it as AB. |
| + | *Draw a perpendicular bisector to this line segment AB. |
| + | *With A as centre construct an arc with 4cm as radius. Mark the intersecting point of arc with the perpendicular bisector as D. Join AD. |
| + | *With B as centre construct another arc with the same radius 4cm. You get the same point D as point of intersection . |
| + | *Join AD and BD which would measure 4cm each and would become one pair of congruent sides of the kite. |
| + | *Similarly draw arcs on the other side taking radius as 6cm to get other pair of congruent sides. |
| + | *ADBE would be the specified kite. |
| | | |
| + | *Developmental Questions: |
| + | #What are the properties of a kite ? |
| + | #What measures are given for constructing a kite ? |
| + | #By which given measure can we begin the kite construction ? |
| + | #What is the angle between the two diagnols in a kite ? |
| + | #For what purpose are we drawing the perpendicular bisector ? |
| + | #What is the purpose of drawing an arc ? |
| + | #What should be measure of the radius of the arc ? |
| + | #Why should AD and BD be same ? |
| + | *Evaluation: |
| + | #Check if the constructed kite satisfies all of its properties. |

| + | #Can you think of any other method of kite construction for the given measures ? |
