Geometry
By: Daanan Hall
Points
Example:
C
• A point is an
exact location.
• This is an
example of a
point.
Lines
• Example:
D
DC
C
• 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.
Example:
• This is a line segment.
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
