## How do you find where two equations intersect?

To find the point of intersection algebraically, solve each equation for y, set the two expressions for y equal to each other, solve for x, and plug the value of x into either of the original equations to find the corresponding y-value.

The values of x and y are the x- and y-values of the point of intersection..

## What is the intersection of two planes called?

lineThe intersection of two planes is called a line. Planes are two-dimensional flat surfaces. For example, a piece of notebook paper or a desktop are…

## Can 2 planes intersect at a point?

The intersection of two planes is a line. … They cannot intersect at only one point because planes are infinite.

## When two planes intersect their intersection is A?

If two planes intersect, then their intersection is a line.

## Why is the intersection of two planes a line?

Solution: In three dimensions (which we are implicitly working with here), what is the intersection of two planes? As long as the planes are not parallel, they should intersect in a line. So our result should be a line.

## When two straight lines intersect adjacent angles are?

(i) When two lines intersect adjacent angles are complementary. Explanation: As the adjacent angles form a linear pair and they are supplementary.

## Do 2 points always create a line?

ANSWER: Never; Postulate 2.1 states through any two points, there is exactly one line. 26. If points M, N, and P lie in plane X, then they are collinear.

## When two infinite planes intersect what do they form?

Answer and Explanation: When two planes intersect, they form a line.

## Are planes infinite?

Plane. A plane may be considered as an infinite set of points forming a connected flat surface extending infinitely far in all directions. A plane has infinite length, infinite width, and zero height (or thickness). It is usually represented in drawings by a four‐sided figure.

## Can three lines intersect at one point?

Terms in this set (6) if three lines intersect at one point then, they are coplanar. if two lines are skew to a third line, then they are skew to each other. two lines that are not coplanar intersect.

## When two straight lines intersect the opposite angles are equal?

When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex.
