An infinitely small representation of location, named with one letter.
What is a point?
100
An angle whose measure is 90 degrees.
What is a right angle?
100
On the same plane.
What is coplanar?
200
Set of points along the y-axis.
What is the vertical?
200
The points on the end of a line segment.
What are endpoints?
200
An angle whose measure is less than 90 degrees.
What is an acute angle?
200
Points, lines, and planes.
What are the building blocks of geometry?
300
m= (y2-y1)/(x2-x1)
What is the slope formula?
300
The point on a segment that is the same distance from both endpoints.
What is a midpoint?
300
An angle whose measure is greater than 90 degrees.
What is an obtuse angle?
300
To divide a shape or line into two congruent shapes or segments.
What is bisection?
400
A number that describes both the direction and the steepness of the line. The direction of a line is either increasing, decreasing, horizontal or vertical.
What is slope?
400
Has length and width, but no thickness. It infinitely expands in both directions.
What is a plane?
400
Angles with the same measure.
What are congruent angles?
400
Things that are arranged following a rule or rules.
What is a pattern?
500
A visual tool that helps you find the slope of a line, with rise and run as the two sides and the line with the missing slope as the hypotenuse.
