(b) The angle in a semi-circle is a complete angle

(c) A circle can have only two parallel tangents

(d) Radius equals to twice of the diameter

I had been asked this question in a job interview.

This question is from Tangent to a Circle topic in division Circles of Mathematics – Class 10

Answer 1

Right option is (c) A circle can have only two parallel tangents

Easiest explanation: A circle can have only two parallel tangents. These two parallel tangents touch either end of the diameter. Hence, ‘A circle can have only two parallel tangents’ is the only correct statement.
