# What are two lines in the same plane that intersect at right angles?

## What are two lines in the same plane that intersect at right angles?

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

### What makes two lines in the same plane intersect?

Two or more lines intersect when they share a common point. If two lines share more than one common point, they must be the same line. If two lines in the same plane share no common point, they must be parallel.

Is it true that if two lines intersect then they are coplanar?

Two lines are parallel lines if they are coplanar and do not intersect. Lines that are not coplanar and do not intersect are called skew lines. Two planes that do not intersect are called parallel planes.

Are intersecting lines in the same plane?

Intersecting: The two lines are coplanar (meaning that they lie on the same plane) and intersect at a single point. Parallel: The two lines are coplanar but never intersect because they travel through different points, while their direction vectors are scalar multiples of one another.

## What are two intersecting planes called?

line
Answer and Explanation: The intersection of two planes is called a line.

### Which must be true if two distinct lines intersect?

If two distinct lines intersect, which MUST be true? the lines form angles at the intersection. There are only three undefined terms in geometry: point, line and plane.

Can 2 skew lines determine a plane?

Two skew lines determine a plane. Three points determine a plane. If three lines are parallel, then they must be coplanar. In a plane, if two lines are perpendicular to the same line, they are parallel.

When does a line and a triangle intersect?

A line and a triangle will intersect in infinitely many points if one side of the triangle is part of the line. You can use what you know about intersecting figures to make conjectures about the ways two or more geometric figures can intersect.

## What happens when two lines intersect in a plane?

two lines intersect in infinitely many points, then they are the same line. You can also explore the ways that other geometric figures intersect in a plane. and the triangle intersect in two points, the rectangle and the circle.

### What are the properties of the intersection of two lines?

Intersection of Two Lines 1. Meaning of Intersection of Two Lines 2. Finding Intersection of Two Lines 3. The Angle of Intersection 4. Conditions for Two Lines to be Parallel 5. Properties of Intersecting Lines

How to calculate the angle of intersection between two lines?

To obtain the angle of intersection between two lines, consider the figure shown: The equations of the two lines in slope-intercept form are: y = (−a1 b1)x +(c1 b1) = m1x +C1 y = (−a2 b2)x +(c2 b2) = m2x +C2 y = ( − a 1 b 1) x + ( c 1 b 1) = m 1 x + C 1 y = ( − a 2 b 2) x + ( c 2 b 2) = m 2 x + C 2
