Question 39

Fill in the blanks to make the statements true.

A ${30}^0-{60}^0-{90}^0$ set square has ___ line/lines of symmetry.

Answer 1

Since a ${30}^0-{60}^0-{90}^0$ set square has a shape of a scalene triangle and a scalene triangle have no line of symmetry because all its sides and angles are of different measures.

Hence, a ${30}^0-{60}^0-{90}^0$ set square has zero line/lines of symmetry.
