Question

If two lines are perpendicular to each other, then the angle between them is dash​

Answer 1

Answer:

90°

If two lines are perpendicular to each other, on both the sides it forms a right angle i.e 90°.

Answer 2

In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
