## What has 2 coplanar angles with a common side a common vertex and no common interior points?

Two coplanar angles with a common side, a common vertex, and no common interior points are called angles.

## What are two angles with measures that have a sum of 90?

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

## Does an angle have two endpoints?

A line segment represents a collection of points inside the endpoints and it is named by its endpoints. A ray is a line that only has one defined endpoint and one side that extends endlessly away from the endpoint. … The angle that is formed by two rays that have the same endpoint is called the vertex.

## What are three ways you can name an angle?

The best way to describe an angle is with three points. One point on each ray and the vertex always in the middle. That angle could be NAMED in three ways: X, BXC, or CXB. Adjacent angles are two angles that have a common vertex, a common side, and no common interior points.

## What are angles which share a common vertex and a common side called?

Two angles are Adjacent when they have a common side and a common vertex (corner point) and don’t overlap. Because: they have a common side (line CB)

## When two lines intersect the opposite angles are?

Vertical angles are pair angles formed when two lines intersect. Vertical angles are sometimes referred to as vertically opposite angles because the angles are opposite to each other.

## Are same side interior angles supplementary or congruent?

Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.

## What is interior of the angle?

1 : the inner of the two angles formed where two sides of a polygon come together. 2 : any of the four angles formed in the area between a pair of parallel lines when a third line cuts them.

## Do linear pairs share a common vertex?

Linear pairs get their name because the sides not common to the two angles form a straight line. Linear pairs always share a common vertex and one common ray, line segment, or line.

## What is a common interior point in geometry?

Definition: The area between the rays that make up an angle, and extending away from the vertex to infinity. … In the figure above, drag the point K and notice that it is in the interior of ∠ABC even beyond the ends of the line segments BA and BC forming the angle.

## What is it called when points lie on the same line?

Three or more points that lie on the same line are collinear points .

## How are 1 and 2 related They are supplementary?

∠1 and ∠2 are supplementary. If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary.

## What are two adjacent angles that make a straight line?

Linear Pairs A linear pair is two angles that are adjacent and whose non-common sides form a straight line. If two angles are a linear pair, then they are supplementary.

## What is an interior angle of a triangle?

60° (for equilateral)Triangle/Internal angle

## Is it possible for a pair of nonadjacent angles to share vertex?

Yes: by definition, two adjacent angles have the same vertex, a side in common and don’t overlap. So, if two angles share the vertex and a side, but they overlap, they are not adjacent.

## Are two angles in the same plane with a common vertex and a common side?

## What type of angle pair is 1 and 3?

Vertical AnglesVertical Angles When two lines intersect at a point, they form two pairs of angles that do not share a side. These pairs are called vertical angles, and they always have the same measure. ∠1 and ∠3 are vertical angles.

## Are all linear pairs always congruent?

Answer Expert Verified. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The sum of a linear pair of angles is 180 degrees, hence are supplementary. Linear pairs of angles can only be congruent when the measure of each of the angles is 90 degrees.
