Study Notes
Congruent Triangles Postulates and Theorems
- Side-Side-Side Congruence Postulate (SSS): Triangles are congruent if all three corresponding sides are equal in measure.
- Side-Angle-Side Congruence Postulate (SAS): Triangles are congruent if two sides and the included angle of one triangle match with the two sides and included angle of another triangle.
- Angle-Side-Angle Congruence Postulate (ASA): Triangles are congruent if two angles and the included side of one triangle correspond to two angles and the included side of another triangle.
- Angle-Angle-Side Congruence Theorem (AAS): Triangles are congruent if two angles and a non-included side of one triangle align with two angles and the corresponding non-included side of another triangle.
- Hypotenuse-Leg Congruence Theorem (HL): For right triangles, congruence is established if the hypotenuse and one leg of one triangle are equal to the hypotenuse and leg of another right triangle.
Angle and Segment Theorems
- Angle Bisector Theorem: A point located on the bisector of an angle is equidistant from the two sides forming that angle.
- Perpendicular Bisector Definition: A perpendicular bisector is a line that intersects a segment at its midpoint and forms right angles to that segment.
- Perpendicular Bisector Theorem: A point on the perpendicular bisector of a segment is equidistant from the segment's endpoints.
Important Theorems to Remember
- Definition of perpendicular lines, which intersects at right angles.
- Right Angles Theorem: All right angles are congruent.
- Corresponding Angles Theorem: When two lines are cut by a transversal, the corresponding angles are equal.
- Definition of midpoint: A point that divides a segment into two equal parts.
- Vertical Angle Theorem: Vertical angles are congruent.
- Alternate Interior Angle Theorem: When two parallel lines are cut by a transversal, the alternate interior angles are congruent.
- Reflexive Property of Congruence: An object is congruent to itself.
