A point is an exact location in space.

A line is a strait path that extends without end in both/opposite directions

A ray is a part of a line that has an end point and extends without ending in the opposite/one direction.

A line segment is part of a line or ray that extends from one end point to another.

A plane is a perfectly flat surface that extend infinitely on all directions.

Congruent is if they have the same shape and size.

An angle is formed by two rays with a common endpoint

The common end point is the vertex

A right angle is an angle that measures exactly 90*

An acute angle is an angle that measures less than 90*

An obtuse angle is an angle that measures more than 90* but less than 180*

A strait is an angle that measures exactly 180*

If the sum of the 2 angles is 90* than the angles are complementary

If the sum of the 2 angles are 180* than the angles are supplementry

Are 2 lines that intersect forming a 90* angle

Some lines in the same plane that do intersect at all

Do not intersect and yet they they are also not parallel

R the opposite angles formed by 2 intersecting lines

Is a line that intersects 2 or more lines 8 angles are formed

Is a set of all points in a plane that are the same distance from a givin point

The given point on a circle is the center of the circle

Part of a circle named by its endpoints

Line segment whose endpoints are the center of the circle

Line segment that passes through the center of the circle

Line segment whose endpoints are any 2 on the circle

• Of a circle is an angle formed
• By 2 radii

Part of circle enclosed by 2 radii
