Geometry Flashcards
What is a “point”?
A location with no size or shape
What is a “Line”?
Made up of points with no thickness or width
What is a “Plane”?
A flat surface made up of points that extends indefinitely in two dimensions
What is a “Line Segment”?
A measurable part of a line consisting of two endpoints and the line between them
What is a “Ray”?
A part of a line that starts at one endpoint and continues indefinitely in one direction
What are “Congruent Segments”?
Two segments that have the same length
What is a “Midpoint”?
The point that is in the exact middle of a line segment
What is a “Bisector”?
A segment, line, or plane that splits a segment or angle in half
What is an “Angle”?
The intersection of two rays at an endpoint
What is a “Vertex”?
The common endpoint of an angle
What are “Congruent Angles”?
Angles that have the same measure
What are “Complementary Angles”?
Angles with measures that add up to 90 degrees
What are “Supplementary Angles”?
Angles with measures that add up to 180 degrees
What are “Adjacent Angles”?
Two angles that share a common side and vertex
What are “Vertical Angles”?
When two lines intersect, these are the angles opposite each other with a common vertex
