Find the number of lines of symmetry for each of the following shapes:
Solution:
We will be using the concepts of the line of symmetry to solve this.
Symmetry states that one shape is identical to the other shape when it is moved, rotated, or flipped.
(a) Here, there are four symmetric lines l, m, n, and o as shown below.
(b) In this figure, there are four symmetric lines p, q, r, and s.
(c) In this figure, u, v, w, and x are the four lines of symmetry.
(d) In this shape only m is the line of symmetry.
(e) Here, a, b, c, d, e, and f are the six lines of symmetry.
(f) In this figure l, m, n, o, p and q are the six lines of symmetry.
(g) This figure has no lines of symmetry.
(h) This figure has no lines of symmetry.
(i) This figure has five lines of symmetry.
