| − | *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.
| |
| − | *Question Corner:
| |
| − | # Can you think of any other method of kite construction for the given measures ?
