Study Notes
Geometry
- Plane: A flat surface extending infinitely in all directions. It's two-dimensional (length and width). Named using a capital letter or three non-collinear points.
- Points: Specific locations, represented by dots. Have no dimensions (no length, width, or thickness). Usually named with capital letters.
- Collinear Points: Points that lie on the same straight line.
- Noncollinear Points: Points that do not lie on the same straight line.
- Coplanar Points: Points that lie on the same plane.
- Noncoplanar Points: Points that do not lie on the same plane.
- Line: A set of infinitely many points in a straight formation. One-dimensional, has infinite length but no width or thickness. Named using two points on the line or a lowercase letter.
- Line Segment: A part of a line with two endpoints.
- Ray: A part of a line with exactly one endpoint, extending infinitely in one direction.
- Angles: Formed when two rays meet at a common endpoint (vertex). Measured in degrees. Named using three capital letters or a number inside the angle.
Types of Angles
- Acute Angle: Greater than 0° and less than 90°.
- Right Angle: Exactly 90°.
- Obtuse Angle: Greater than 90° and less than 180°.
- Supplementary Angles: Two angles whose measures add up to 180°.
- Complementary Angles: Two angles whose measures add up to 90°.
- Adjacent Angles: Two angles that have a common vertex and a common side.
- Vertical Angles: A pair of non-adjacent angles formed by the intersection of two lines. Vertical angles are congruent (have the same measure).
