PRESENTATION OUTLINE
Point
A location in space
An example of a point is a period
Line
A straight, continuous arrangement of points
An example of a line is that a square has 4 lines
Plane
A flat service. It has infinite length and width but no depth.
An example of a plane is any 2-d shape
Coplanar Lines
Two or more lines that are located in the same plane.
An example would be parallel lines
Skew Lines
Lines that are not on the same plane.
An example is the opposite of a Coplanar Line.
Arc
Part of a circle. It's the curve between 2 points on a circle.
An example of an arc is a dome.
Congruent
To have the same size, shape, and measure
An example is two identical squares.
Angle
Two Rays that share a common endpoint.
An example is half of a square
Vertex
The vertex of an angle is the common endpoint 2 Rays share.
Example-The vertex of angle BDA is D.
Acute Angle
An angle whose measure is greater than 0 degrees, but less than 90 degrees.
Obtuse Angle
An angle whose measure is greater than 90 degrees, but less than 180 degrees.
Right Angle
An angle whose measure is 90 degrees
Straight Angle
An angle whose measure is 180 degrees
Congruent Angles
Two or more angles that have equal measures
Supplementary Angles
Two angles are supplementary angles if the sum of their angle measures is equal to 180 degrees
Complimentary Angles
Two angles are complimentary angles if the sum of their angle measures is equal to 90 degrees
Perpendicular
Two lines, line segments, or rays are perpendicular if they intersect to form 90 degree angles
Adjacent Angles
Two angles that share a common vertex and share a common side
