Study Notes
Theorems and Postulates
- Congruent Complement Theorem: States that if two angles each complement a third angle, those two angles are congruent.
- Congruent Supplements Theorem: States that if two angles each supplement a third angle, those two angles are congruent.
- Segment Addition Postulate: If point B lies between points A and C, then the lengths satisfy the relationship AB + BC = AC.
- Angle Addition Postulate: Explains how the sum of the measures of two angles that share a common side must equal the measure of the whole angle formed.
- Linear Pair Postulate: If two angles form a linear pair (sharing a vertex and a side), then their measures add up to 180 degrees.
Definitions
- Midpoint: A point B is the midpoint of segment AC if the lengths AB and BC are equal.
- Angle Bisector: A ray that divides an angle into two equal parts creates two congruent angles.
- Vertical Angles: These are the angles opposite each other when two lines intersect, and they are always congruent.
- Complementary Angles: Two angles that add up to 90 degrees are termed complementary.
- Supplementary Angles: Two angles that add up to 180 degrees are referred to as supplementary.
- Perpendicular Lines: Defined as two lines that intersect to create a right angle.
- Right Angle Congruence Theorem: States that all right angles are congruent to one another.
Key Concepts
- Vertical angles are always congruent, providing a basis for angle relationships in intersecting lines.
- The properties of complementary and supplementary angles are crucial for solving numerous geometric problems.
