## What’s the straight line without dots called?

Answer: A line goes without end in both directions but a ray has one endpoint and goes without end in one direction.

The line AB is same as the line BA..

## What is the union of two rays that have a common endpoint called?

angleAn angle is the union of two noncollinear rays with a common endpoint. The common endpoint is called the vertex of the angle, and the rays are called the sides of the angle.

## What do two rays make?

When two rays share an endpoint, an angle is formed. Angles can be described as acute, right, obtuse, or straight, and are measured in degrees.

## What are two lines that intersect to form right angles?

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

## What is the set of all points?

Page 1. Definition: A circle is the set of all points in a plane that are equidistant from a given point called the center of the circle. We use the symbol ⊙ to represent a circle. The a line segment from the center of the circle to any point on the circle is a radius of the circle.

## Is the union of two rays is always a line?

An angle is the union of two rays with a common endpoint. The common endpoint of the rays is called the vertex of the angle, and the rays themselves are called the sides of the angle. … So, together a pair of opposite rays always forms a straight line.

## Do two rays always define a plane?

If the union of two rays is a line, then the rays are opposite rays. … Through any two points there is exactly one line. Three Points determine a plane. Through any three points not on a line there is exactly one plane.

## What is Angle ABC?

Angle ABC is a straight angle, or 180°. Angle f, g, and h together must add to 180°. Try again. Angle ABC is a straight angle, or 180°.

## What’s the common endpoint of two rays?

An angle is formed by two rays with a common endpoint. Each ray is called an arm of the angle. The common endpoint is called the vertex of the angle.

## What is the part of a line that contains two points and all other points between them?

Segment – part of a line that consists of two points called endpoints and all points between them.

## What is the endpoint of a ray?

A ray starts at a given point and goes off in a certain direction forever, to infinity. … The point where the ray starts is called (confusingly) the endpoint. On its way to infinity it may pass through one or more other points.
