A Kite and its properties

Learning objectives
<K = <M. This is the only pair of congruent angles because <J and <L have different measures.
 * 1) A kite is a quadrilateral with two distinct pairs of adjacent sides that are congruent.
 * 2) The two pairs of congruent sides meet at two different points.
 * 3) A kite can also be described as a quadrilateral with an axis of symmetry along one of its diagonals.
 * 4) Kites have a couple of properties that will help us identify them from other quadrilaterals.
 * The diagonals of a kite meet at a right angle.
 * Kites have exactly one pair of opposite angles that are congruent.
 * Diagnols intersect at right angles.



Notes for teachers
Source : http://www.ask.com/question/what-is-a-kite-in-geometry Summary :
 * 1) A kite is sometimes also known as a deltoid.
 * 2) A kite, may be either convex or concave, but the word "kite" is often restricted to the convex variety. A concave kite is sometimes called a "dart" or "arrowhead".

Activity No # 1. Paper kite
This activity has been taken from the website : http://www.transum.org/software/Fun_Maths/kite/
 * Estimated Time: 30 minutes.
 * Materials/ Resources needed :
 * 1) A4 sheet of paper.
 * Prerequisites/Instructions, if any
 * 1) Neat paper folding skills.
 * 2) Ability to follow instructions.
 * Multimedia resources
 * Website interactives/ links/ / Geogebra Applets
 * Process:
 * 1) Fold an A4 sheet of paper as shown in the figures to make a kite.




 * Developmental Questions:
 * 1) Which is the figure formed ?
 * 2) What is special about this quadrilateral ?
 * 3) How many sides does a kite have ?
 * 4) Are all sides equal ?
 * 5) Mark the diagnols ? What do you notice about them ?
 * Evaluation:
 * 1) Were the students able dto recognise the properties of a kite.
 * Question Corner
 * 1) Compare kite with other quadrilaterals and make a list of similarities and differences between them.
