Question. 32

A horizontal line and a vertical line always intersect at right angles.

Answer:

true

Detailed Answer with Explanation:

Understand the two types of lines first.

• A horizontal line goes left–right (like the horizon).

• A vertical line goes up–down.

Now use the definitions step by step.

  1. A horizontal line is parallel to the x-axis.
  2. A vertical line is parallel to the y-axis.
  3. By definition, horizontal and vertical directions are perpendicular.
  4. Perpendicular lines meet to form a right angle.
  5. A right angle measures (90^circ).

Therefore, when a horizontal line meets a vertical line, the angle at their intersection is (90^circ).

So, the statement is true.
