Study Notes
Basic Geometry Terms
- Point: A location defined with no dimensions—no shape or size.
- Line: A straight path composed of an infinite number of points; has no thickness or width.
- Plane: A two-dimensional flat surface made of points, extending infinitely in all directions.
Relationships Between Points
- Collinear: Describes points that are all located on the same straight line.
- Coplanar: Refers to points that all lie within the same flat surface (plane).
Line Segments and Distance
- Line Segment: A measurable portion of a line consisting of two defined endpoints.
- Distance Formula: A mathematical formula used to calculate the distance between two points on a coordinate plane.
Segments and Midpoints
- Congruent Segments: Segments that possess equal length.
- Midpoint Formula: A method for determining the midpoint between two endpoints of a line segment.
- Segment Bisector: Can be a segment, line, or plane that intersects a segment precisely at its midpoint.
Rays and Angles
- Ray: A part of a line that begins at a point and extends indefinitely in one direction.
- Angle: Formed by the intersection of two rays that share a common endpoint, known as the vertex.
- Vertex: The specific point where two rays or lines meet to form an angle.
Types of Angles
- Right Angle: An angle measuring exactly 90 degrees.
- Acute Angle: An angle measuring less than 90 degrees.
- Obtuse Angle: An angle measuring between 90 degrees and 180 degrees.
- Congruent Angles: Angles that have the identical measurement.
Angle Relationships
- Adjacent Angles: Angles that share a common side and vertex.
- Vertical Angles: Formed by two intersecting lines, located directly opposite each other.
- Complementary Angles: Two angles whose measurements add up to 90 degrees.
- Supplementary Angles: Two angles whose measurements sum to 180 degrees.
- Linear Pair: A pair of adjacent angles that are supplementary.
Special Angle Relationships
- Perpendicular Lines: Lines that intersect forming four right angles (90 degrees).
- Angle Bisector: A ray that divides an angle into two smaller angles of equal measure.
