## What is Pendicular line?

## What is Pendicular line?

Perpendicular lines are lines that intersect at a right (90 degrees) angle.

**What are two non-perpendicular intersecting lines called?**

Non-Perpendicular Intersecting Lines When two lines intersect, they create vertical angles, sometimes called opposite angles, that are congruent.

### What is perpendicular lines example?

Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol used to denote two perpendicular lines: ⊥ ⊥ .

**How do you know if a line is not perpendicular?**

Perpendicular lines intersect at right angles to one another. To figure out if two equations are perpendicular, take a look at their slopes. The slopes of perpendicular lines are opposite reciprocals of each other. Their product is -1!

#### What does ⊥ mean in math?

Perpendicular lines

Perpendicular lines are lines, segments or rays that intersect to form right angles. The symbol ⊥ means is perpendicular to .

**What are coinciding lines?**

Two lines that lie on top of one another are called coincident lines.

## What are intersecting and perpendicular lines?

Two or more lines that meet at a point are called intersecting lines. That point would be on each of these lines. In Figure 1, lines l and m intersect at Q. Two lines that intersect and form right angles are called perpendicular lines.

**Which shapes are perpendicular?**

As listed before, the most common shapes with perpendicular sides are squares and rectangles. Another common shape with perpendicular sides is the right triangle. It is called a right triangle because it has a right angle for one of its three angles, this is where the perpendicular sides meet.

### How do you tell if a line is neither parallel or perpendicular?

If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

**How do you prove a line is perpendicular?**

If the two lines intersect at a point, the vertical angles formed are congruent. The intersecting lines either form a pair of acute angles and a pair of obtuse angles, or the intersecting lines form four right angles. When the lines meet to form four right angles, the lines are perpendicular.
