Study Notes
Geometry Vocabulary Study Notes
-
Line: A set of points collinear to two distinct points, extending infinitely in both directions.
-
Segment: Consists of two endpoints and all points in between, representing a finite portion of a line.
-
Plane: A flat, two-dimensional figure with no thickness that extends indefinitely in all directions.
-
Ray: A line that has one endpoint (or point of origin) and extends infinitely in one direction.
-
Acute Angle: An angle measuring less than 90 degrees.
-
Vertex: The common point where two rays meet to form an angle.
-
Midpoint: The exact middle point of a line segment, equidistant from both endpoints.
-
Obtuse Angle: An angle that is greater than 90 degrees but less than 180 degrees.
-
Complementary Angles: Two angles whose measures add up to 90 degrees.
-
Supplementary Angles: Two angles whose measures add up to 180 degrees.
-
Angle: Formed by two non-collinear rays that share a common endpoint, known as the vertex.
-
Perpendicular Lines: Lines that intersect to form a right angle (90 degrees).
-
Vertical Angles: Two non-adjacent angles created when two lines intersect, having equal measures.
-
Straight Angle: An angle formed by opposite rays, measuring exactly 180 degrees.
-
Congruent: Geometric elements (angles, segments) that are of equal measure.
-
Coplanar Points: Points that lie within the same geometric plane.
-
Collinear Points: Points that lie on the same straight line.
-
Adjacent Angles: Two angles that share a common side and have no interior points in common.
-
Point: A precise location in a plane, typically represented by a dot; has no dimensions.
-
Parallel Lines: Coplanar lines that never intersect and remain equidistant from each other.
-
Bisector: A line that divides an angle or segment into two equal parts.
-
Intersecting Lines: Lines that meet or cross at a single point.
-
Origin: The point in the coordinate plane represented by (0,0).
-
Coordinate Plane: A two-dimensional plane divided into four regions by a horizontal line (x-axis) and a vertical line (y-axis).
-
Quadrant: One of the four sections formed in the coordinate plane.
-
Distance: The length of the shortest path between two points, measurable in units.
-
Skew Lines: Lines that do not intersect and are not coplanar.
