Question

Two lines are said to be __________ if they intersect each other at right angles.​

Answer 1

Answer:

perpendicular

Step-by-step explanation:

the interaction of line at 90 degree are called perpendicular lines whereas intersection of lines at any degree other than 90 are called intersecting lines

Answer 2

Answer:

Two lines are said to be perpendicular if they intersect each other at right angles.

Step-by-step explanation:

If two lines intersect at an angle of 90 degrees, they are said to be perpendicular. And, if two angles form an angle of 90 degrees, they are said to be right angles, as one right angle is equal to 90 degrees. So, we can also say that if two lines intersect each other at right angles, they are said to be perpendicular to each other.
