Real-World Examples of Special Angle Pairs in Everyday Life

📚 Quick Study Guide

• 📐 Complementary Angles: Two angles whose measures add up to $90^{\circ}$.
• 🤝 Supplementary Angles: Two angles whose measures add up to $180^{\circ}$.
• ✨ Vertical Angles: Two angles formed by intersecting lines that are opposite each other; they are always congruent (equal).
• 👯 Corresponding Angles: Angles that occupy the same relative position at each intersection where a transversal crosses two lines. If the two lines are parallel, these angles are congruent.
• 🚗 Alternate Interior Angles: Angles on opposite sides of the transversal and inside the two lines. If the two lines are parallel, these angles are congruent.
• 🛤️ Alternate Exterior Angles: Angles on opposite sides of the transversal and outside the two lines. If the two lines are parallel, these angles are congruent.
