Q6) Trace each figure and draw the lines of symmetry, if any:

i)

ii)

iii)

iv)

Q8) Given here are figures of a few

folded sheets and designs drawn

about the fold. In each case, draw a

a rough diagram of the complete

figure that would be seen when the

design is cut off.

Q1) Find the number of lines of symmetry for each of the following shapes:

v)

vi)

vii)

viii)

ix)

Q2) Copy the triangle in each of the following figures on squared paper. In each case,

draw the line(s) of symmetry, if any and identify the type of triangle. (Some of

you may like to trace the figures and try paper-folding first!)

Q3) Complete the following table.

Q4) Can you draw a triangle which has

(a) exactly one line of symmetry?

(b) exactly two lines of symmetry?

(c) exactly three lines of symmetry?

(d) no lines of symmetry?

Sketch a rough figure in each case.

Q5) On a squared paper, sketch the following:

(a) A triangle with a horizontal line of symmetry but no vertical line of symmetry.

(b) A quadrilateral with both horizontal and vertical lines of symmetry.

(c) A quadrilateral with a horizontal line of symmetry but no vertical line of

symmetry.

(d) A hexagon with exactly two lines of symmetry.

(e) A hexagon with six lines of symmetry.

Q7) Consider the letters of English alphabets, A to Z. List among them

the letters which have

(a) vertical lines of symmetry (like A)

(b) horizontal lines of symmetry (like B)

(c) no lines of symmetry (like Q)
