Study Notes
Angles and Relationships
- Complementary angles sum to 90 degrees.
- Acute angles measure between 0 and 90 degrees.
- Obtuse angles measure between 90 and 180 degrees.
- Supplementary angles sum to 180 degrees.
- Vertical angles are congruent angles formed by intersecting lines.
Geometric Terms
- An angle bisector divides an angle into two congruent angles.
- A midpoint is defined as the point that divides a segment into two congruent segments.
- A segment is part of a line with two endpoints.
- A ray has one endpoint and extends indefinitely in one direction.
Lines and Planes
- A line extends indefinitely in both directions without end.
- Points that lie on the same line are termed collinear.
- Coplanar points exist within the same plane.
- Perpendicular lines intersect at right angles (90 degrees).
Mathematical Formulas and Theorems
- The distance formula calculates the distance between two points in a coordinate plane.
- Segment addition postulate states if B is between A and C, then AB + BC = AC.
Angles and Point Relationships
- Adjacent angles share a common vertex and side but do not overlap.
- Opposite rays share a common endpoint and form a straight line.
- The intersection of two planes is a line.
Additional Concepts
- A point represents a location with no size, shape, or dimension.
- A plane is a flat surface that extends infinitely in all directions.
- A space represents a set of all points in a given context.
