Question 16

Out of the given four options, only one is correct. Write the correct answer.

The number of lines of symmetry in a ${30}^0-{60}^0-{90}^0$ set square is

(a) 0 (b) 1 (c) 2 (d) 3

Answer 1

The "Line of Symmetry" is the imaginary line where you could fold the image and have both halves match exactly.

Since a ${30}^0-{60}^0-{90}^0$ set square has a shape of a scalene triangle and a scalene triangle has zero line of symmetry.

Hence, the correct answer is option (a).
