Question

If Line JK is perpendicular to Line LM, which of the following statements are true?

A. JK and LM are coplanar and do not intersect.
B. JK and LM meet at a straight angle.
C. JK and LM meet at a right angle.
D. JK and LM are not in the same plane.

Answer 1

(C)

Explanation:

It is given that JK is perpendicular to LM, since JK and LM both are lines which lie in the same plane, therefore JK and LM are coplanar.

Since JK is perpendicular to LM, then JK and LM will intersect.

Thus, option A is not correct.

And, as JK is perpendicular to LM, then they will meet each other at a right angle as perpendicular lines make a right angle with each other.

Thus, Option C is correct.

Answer 2

If Line JK is perpendicular to Line LM,they meet at a right angle (90 degrees).
So,
The best answer is :
C. JK and LM meet at a right angle.
