Question

Make a shape of parallelogram, kite, rhombus, square, trapeziu zium and rectangle by using colour paper or scrap book paper or Ay sheet paper in a colourful way along with marking the diagonals in these. Paste the shapes class work noter. and in the write the properties along then rides.​

Answer 1

Answer:

• A simple closed curve made up of only line segments is called a

polygon.

• A diagonal of a polygon is a line segment connecting two non-

consecutive vertices.

• A convex polygon is a polygon in which no portion of its any

diagonal is in its exterior.

• A quadrilateral is a polygon having only four sides.

• A regular polygon is a polygon whose all sides are equal and also

all angles are equal.

• The sum of interior angles of a polygon of n sides is (n-2) straight

angles.

• The sum of interior angles of a quadrilateral is 360°.

• The sum of exterior angles, taken in an order, of a polygon is 360°.

• Trapezium is a quadrilateral in which a pair of opposite sides is

parallel.

• Kite is a quadrilateral which has two pairs of equal consecutive

sides.

• A parallelogram is a quadrilateral in which each pair of opposite

sides is parallel.

• A rhombus is a parallelogram in which adjacent sides are equal.

• A rectangle is a parallelogram in which one angle is of 900.

• A square is a parallelogram in which adjacent sides are equal and

one angle is of 900.

• In a parallelogram, opposite sides are equal, opposite angles are

equal and diagonals bisect each other.

• In a rhombus diagonals intersect at right angles.

• In a rectangle diagonals are equal.

• Five measurements can determine a quadrilateral uniquely.

• A quadrilateral can be constructed uniquely if the lengths of its

four sides and a diagonal are given.

• A quadrilateral can be constructed uniquely if the lengths of its

three sides and two diagonals are given.

• A quadrilateral can be constructed uniquely if its two adjacent

sides and three angles are given.

• A quadrilateral can be constructed uniquely if its three sides and

two included angles are given.
