Geometric Figures
A figure that extends endlessly in both directions.
Line
Solve for x:
2x + 16 = 30
x = 7
A tool used to measure angles.
Protractor
An angle that equals exactly 90 Degrees
Right Angle
What is Mr. Kaiser's favorite NFL team?
Pittsburgh Steelers
This has one endpoint and extends endlessly in the other direction.
Ray
Solve for x:
5x - 10 = 4x + 28
x = 38
angles formed by intersecting lines
vertical angles
An angle that is greater than 0 degrees but less than 90 degrees
Acute angle
What sport does Mr. Kaiser coach here at Erie High School?
Basketball
This is a part of a line that has two endpoints.
Line Segment
solve for y:
2y + 4y + 10 = 3y + 28
y = 6
angles that have the same measure
congruent angles
An angle that equals exactly 180 degrees
Straight angle
How many children does Mr. Kaiser have?
A single location on a Line, these are used to name geometric figures
Point
solve for x:
2x - x + 24 = 90
x = 66
A pair of angles whose measures have a sum of 180 degrees
Supplementary Angles
Two angles that have a common vertex and a common ray
Adjacent Angles
How old is Mr. Kaiser?
31
These are formed by two rays that share a common endpoint.
Angle
Solve for x:
4x = 80 + 2x
x = 40
A line that intersects two different lines at two different points.
Transversal
A pair of angles whose measures have a sums of 90 degrees
Complementary angles
