Question

If two lines are perpendicular, then____________​

Answer 1

Step-by-step explanation:

If two lines are perpendicular, the slopes are negative reciprocals. (The product of the slopes = -1.) since their slopes of 0 have undefined reciprocals. Vertical and horizontal lines are perpendicular.

Answer 2

Answer:

Two lines are perpendicular or orthogonal if they meet at right angles. For two perpendicular lines, all four angles formed by the two lines are equal to 9 0 ∘ 90 ^ \circ 90∘. Two non-vertical lines are perpendicular if and only if the product of their slopes is -1.
