Complete the table: Figure Number of lines of symmetry Order of rotational symmetry Equilateral triangle

We know that, A figure, whose one half is exactly same shape and size as the other half, is known as symmetrical figure. Also, A line of symmetry is the line that divides an object or a shape in two identical halves. Given shape: An equilateral triangle. Given below is the diagram for an equilateral triangle with the lines of symmetry, The number of times a figure fits into itself in one complete rotation is called the order of rotational symmetry. The given shape produces original shape three times if it is rotated as shown. Hence, the completed table is given below. Figure Number of lines of symmetry Order of rotational symmetry Equilateral triangle 3 3
