Measuring Segments and Angles

Vocabulary

• Lines-an infinite number of points on a straight path that extends in two opposite directions with no end and has no thickness.

• Segment- the part of a line that consists of two points, called endpoints and all points between them

• Rays- the part of a line that consists of one endpoint and all the points of the line on one side of the endpoint

• Plane- an infinite number of points and lines on a flat surface that extends without end and has no thickness

​Vocabulary

​

• ​Angle: formed by two rays with the same endpoint which is called the vertex

• ​Opposite Rays: rays with the same endpoints that lie on the same line

• ​A point is a location and has no size
