Test: Symmetry - Class 7 MCQ

Equilateral triangles have all three sides equal and all three angles equal showing 3 lines of symmetry.

A rectangle has two lines of symmetry as shown in the figure. A rectangle can be folded into half either horizontally or vertically.

A regular hexagon with six equal sides has six lines of symmetry. For all regular polygons, the number of lines of symmetry is equal to the number of sides. That is an equilateral triangle has 3 lines of symmetry, a square has 4 lines of symmetry, similarly, a regular hexagon has 6 lines of symmetry.

H, I, O, X are the letters having a reflectional symmetry about both the vertical mirror and the horizontal mirror.

A line of symmetry is the line that divides the shape into two halves that match exactly. A square has four lines of linear symmetry. One crosses through each diagonal. The other is the two lines that cross horizontally and vertically through the middle of the square.

lines of symmetry of a regular pentagon has 5 lines of symmetry.

Isosceles triangle has only one line of symmetry.

The number of times a figure fits into itself in one complete rotation is called the order of rotational symmetry. A figure has a rotational symmetry of order 1, if it can come to its original position after full rotation or 360º.

The angle of rotation of an Equilateral Triangle is 120º

A rectangle is symmetrical about the lines joining the mid point of the opposite sides.
