draw and write the properties of following shapes. kite, trapezium, rhombus, cyclic quadrilaterals,
- It has two diagonal which intersect each other at right angle
- A kite is symmetrical about its main diagonal
- The shorter diagonal divides the kite into 2 isosceles triangle
- It cam be viewed as a pair of congruent triangle with common base
- The two angles are equal where the unequal sides meet
- The parallel sides ate called bases
- The other non-parallel sides are called legs
- If the two non parallel sides are equal and form equal angles at one of the bases ,the trapezium is an isosceles trapezium
- All sides of rhombus are equal
- The opposite sides of rhombus are equal
- opposite angles of rhombus are equal
- in a rhombus diagonals bisect each other at right angle
- Diagonals of rhombus bisect the angles
- within a rhombus ,there can be no inscribing circle
- The sum of two adjacent angles is equal to 180 °
- In a cyclic quadrilateral ,the sum of a pair of opposite angle is 180°
- If the sum of the two opposite angle are supplementary ,then it's a cyclic quadrilateral
- The area of cyclic quadrilateral is
- = √(s-a)(s-b)(s-c)(s-d)
- The four vertices of a cyclic quadrilateral lie on the circumference of the circle
