Study Notes
Angle Types
- Right Angle: Measures exactly 90 degrees.
- Obtuse Angle: Measures between 90 and 180 degrees.
- Acute Angle: Measures less than 90 degrees but greater than 0 degrees.
Angle Relationships
- Complementary Angles: Two angles that sum to 90 degrees.
- Supplementary Angles: Two angles that sum to 180 degrees.
- Vertical Angles: Formed by intersecting lines; they are opposite and congruent.
Transversals and Lines
- Transversal: A line that intersects two parallel lines.
- Interior Angles: Angles formed inside the area created by the transversal and the parallel lines.
- Exterior Angles: Angles formed outside the area created by the transversal and the parallel lines.
Specific Angle Types with Transversals
- Alternate Exterior Angles: Located outside the parallel lines on opposite sides of the transversal; these angles are congruent.
- Alternate Interior Angles: Found inside the parallel lines on opposite sides of the transversal; these angles are also congruent.
- Consecutive (Same-Side) Interior Angles: Interior angles located on the same side of the transversal; these angles are supplementary.
- Corresponding Angles: Located at matching positions when a transversal crosses parallel lines; these angles are congruent.
