Geometry

Points

Example:

C

• A point is an exact location.

• This is an example of a point.

Lines

• Example:

D C

DC

• A line is a straight path that extends without end in opposite directions.

• This is a line.

Planes

• A plane is a flat surface that extends without end in every direction.

• This is a plane.

Line Segment

• A LINE SEGMENT HAS TWO ENDPOINTS.

• This is a line segment.

Example:

F

G

Ray

• A ray has one endpoint. From the endpoint, the ray extends forever in one direction only.

• This is a ray.

Example:

Parallel Lines

• Parallel lines are lines in a plane that are always the same distance apart.

• This is an example.

Example:

Intersecting Line

• Intersecting Lines cross at exactly one point.

• Look on your right to see an example of a intersecting line.

Example:

Perpendicular Lines

• Perpendicular Lines intersecting to form 90 degree angles,or right angles.

• Here is a perpendicular line.

Example:

Skew

• Skew lines are lines that are not in the same plane,are not parallel, and do not intersect.

• This is a Skew line.

Example:

Acute Angles

• An acute angle measures less than 90 degrees.

• This is an acute angle

Right Angles

• A right angle measure 90 degrees.

• This is a right angle

Obtuse Angles

• An obtuse angle measures more than 90 degrees but less than 180 degrees.

• This is an obtuse angle.

Straight Angles

• A straight angle measure 180 degrees.

• This is a straight angle.

That is my show now clap
