Question

In the sentence " MATHS ALL AROUND " , find the letters with :
1 ) line symmetry .
2 ) rotational symmetry .
3 ) both line and rotational symmetries .

Answer 1

Step-by-step explanation:

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged. A square has 4 lines of symmetry, as shown below.

Rotational symmetry, also known as radial symmetry in biology, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation.

An equilateral triangle has both line and rotational symmetry of order more than 1. ... (ii) An isosceles triangle has only one- line symmetry and no rotational symmetry of order more than 1. 1. (iii) Parallelogram has two order of rotational symmetry but no line of symmetry.
