What is the angle formed by two perpendicular lines?
Answer:
90°
- Let us look at the definition of perpendicular lines:
When a straight line stands on another straight line in such a way that the two adjacent angles formed are equal to 90 degrees, those two lines are called perpendicular lines. - As an example, let us look at the following figure:
In the above figure, the line AB is perpendicular to the line PQ, The angles formed by these two lines are:
∠PSA, ∠QSA, ∠BSP and ∠BSQ.
All four angles are right angles, i.e., 90 degrees.
