Here there are many points.
A point is an exact location in space.
A line is a straight path of points that goes on and on in two directions.
A line segment is a part of a line. It has two endpoints.
Line
A ray is a part of a line. It has one endpoint and continues on and on in only one direction.
An angle is formed by 2 rays that have the same end point.
The common end point is called the vertex.
A Protractor is used to measure the size of angles. It measures in degrees.
Circumference
Diameter
Chord
Radius
The diameter goes through the center of the circle.
The diameter is any line segment that connects two points on the circle and passes through the center.
RADIUS Must touch the center
The radius is any line segment that connects the center to a point on the circle.
ChordDoes not go through the center.
A chord is any line segment that connects two points on the circle.
