A square has 4 lines of symmetry as it has 4 equal sides and 4 equal lines.
How many lines of symmetry will a general quadrilateral have?
General quadrilateral has no line of symmetry.
How many lines of symmetry will a kite have? Draw the lines of symmetry of a kite.
A kite has only one line of symmetry which will be the bisector of ∠A and ∠C of the kite quadrilateral ABCD in which AB = AD and BC = DC
How many lines of symmetry will an isosceles trapezium have? Draw these lines. (An isosceles trapezium is one whose non-parallel sides are equal).
Isosceles trapezium ABCD in which AD = BC and AB ∥ DC has only one line of symmetry ‘l’ which is the perpendicular bisector of AB and DC.
