Transversal lines and angles quiz for 7th graders

📐 Quick Study Guide

• 🧭 A transversal line intersects two or more lines.
• 👯‍♀️ When a transversal intersects two lines, it creates several angle pairs: corresponding angles, alternate interior angles, alternate exterior angles, and same-side interior angles.
• 🤝 Corresponding angles are in the same position relative to the transversal and the intersected lines. If the lines are parallel, corresponding angles are congruent (equal).
• ✨ Alternate interior angles are on opposite sides of the transversal and inside the two lines. If the lines are parallel, alternate interior angles are congruent.
• 🌀 Alternate exterior angles are on opposite sides of the transversal and outside the two lines. If the lines are parallel, alternate exterior angles are congruent.
• 🚗 Same-side interior angles are on the same side of the transversal and inside the two lines. If the lines are parallel, same-side interior angles are supplementary (add up to $180^\circ$).
• ➕ Supplementary angles add up to $180^\circ$.
• 📐 Congruent angles have the same measure.
