Draw the figure and write the number of lines of symmetry: Shape Draw a small figure Number of lines of symmetry Equilateral triangle

Any object or shape which can be cut in two equal halves in such a way that both the parts are exactly the same is called symmetrical. The line which divides the shape is called the symmetry. So, if we place a mirror on the line of symmetry we can see the complete image. When a symmetrical shape is folded along the line of symmetry, one half of the shape exactly lies over the other half which shows that one half of the shape is exactly the same as the other half. We know that, a triangle with 3 lines of symmetry is known as an equilateral triangle. A triangle with all three equal sides are known as equilateral triangle. As, there are three equal sides, it has three lines of symmetry. A line drawn from vertex to the mid-point of opposite side is the line of symmetry. Shape Small figure No.of lines of symmetry Equilateral triangle 3

Draw the figure and write the number of lines of symmetry: Shape Draw a small figure Number of lines of symmetry Isosceles triangle

Any object or shape which can be cut in two equal halves in such a way that both the parts are exactly the same is called symmetrical. The line which divides the shape is called the symmetry. So, if we place a mirror on the line of symmetry we can see the complete image. When a symmetrical shape is folded along the line of symmetry, one half of the shape exactly lies over the other half which shows that one half of the shape is exactly the same as the other half. Consider an isosceles triangle, in which two sides are equal. The line drawn from the vertex of the equal side to mid-point of other side divides it into two equal halves. So, an isosceles triangle have only one line of symmetry. Shape Small figure No.of lines of symmetry Isosceles triangle 1

Draw the figure and write the number of lines of symmetry: Shape Draw a small figure Number of lines of symmetry Square

Any object or shape which can be cut in two equal halves in such a way that both the parts are exactly the same is called symmetrical. The line which divides the shape is called the symmetry. So, if we place a mirror on the line of symmetry we can see the complete image. When a symmetrical shape is folded along the line of symmetry, one half of the shape exactly lies over the other half which shows that one half of the shape is exactly the same as the other half. We know that, a quadrilateral having four lines of symmetry is a square. A square is a quadrilateral having four equal sides and equal diagonals. So, the lines drawn from mid-point of opposite sides and two diagonals divides the square into two equal parts. Shape Small figure No.of lines of symmetry Square 4

Draw the figure and write the number of lines of symmetry: Shape Draw a small figure Number of lines of symmetry Rectangle

Any object or shape which can be cut in two equal halves in such a way that both the parts are exactly the same is called symmetrical. The line which divides the shape is called the symmetry. So, if we place a mirror on the line of symmetry we can see the complete image. When a symmetrical shape is folded along the line of symmetry, one half of the shape exactly lies over the other half which shows that one half of the shape is exactly the same as the other half. We know that, a rectangle has two lines of symmetry. Rectangle is a quadrilateral with opposite sides are equal and diagonals also equal. We know that, a rectangle has two lines of symmetry. i.e. as the lines drawn from mid-point of opposite sides of the rectangle. Shape Small figure No.of lines of symmetry Rectangle 2
