Geometry Basics 1
A line that connects two points
What is a line segment
A straight line that makes the right angle (90 degrees) with the other line (it intersects with another line)
What is a perpendicular line
An angle of exactly 90 degrees
What is a right angle
Two angles whose sum is 180 degrees
What are supplementary angles
What formula is shown in letter A?
What is Midpoint Formula
A line with a single endpoint
What is a ray
What is a parallel line
An angle that is greater than 90 degrees
What is an obtuse angle
A pair of adjacent angles formed when two lines intersect
What is a linear pair
What formula is shown in letter B?
What is Distance Formula
Points that lie on the same straight/single line
What is collinear
an object with an initial point, an end point, and a direction
An angle that is less than 90 degrees
What is an acute angle
Angles that lie opposite to each other when two lines intersect
What formula is shown in letter C?
What is Segment Partitioning Formula
Points that exist on the same plane
What is coplanar
a line, ray, or segment that cuts another line segment at the center dividing the line into two equal halves
What is segment bisector
The point where two or more lines meet
A line that splits an angle into two equal angles
What is angle bisector
A shape with the same shape and size of another shape
What is congruent
the length of a line segment divided into smaller pieces is the sum of the lengths of all those smaller segments
What is segment addition postulate
Angles with a common (shared) side and common (shared) vertex
What are adjacent angles
The sum of two adjacent angle measures will equal the angle measure of the larger angle that they form together
What is angle addition postulate
