2. Draw the following.
(a) A triangle with exactly one line of symmetry.

(b) A triangle with exactly three lines of symmetry.
(c) A triangle with no line of symmetry.
Is it possible to draw a triangle with exactly two lines of symmetry? (NCERT)
3. Draw the following. In each case, the figure should contain at least one curved boundary.
(a) A figure with exactly one line of symmetry. (b) A figure with exactly two lines of symmetry.
(c) A figure with exactly four lines of symmetry. (NCERT)
4. In the given figure, the mirror images (reflection) of the letters ‘A’ and
‘B’ are shown along a vertical dotted line. Find the same mirror image B B
for the letters P, H, L, T, S, V, X.
Find out which letters look the same after reflection (i.e., which letters
look the same in the image) and which do not. Can you guess why?
