Nivriti Rathi - Recap Mind Map - Lines & Angles

1. There are many angles formed when a transversal cuts through a pair of parallel lines.

   • Co-interior Angles
   • Co-exterior Angles
   • Vertically Opposite Angles
   • Alternate Interior Angles
   • Alternate Exterior Angles
   • Linear Pair

2. Parallel lines are always the same distance apart and they never intersect.

3. A transversal is a line which passes through a pair of parallel lines.

   • Alternate Exterior Angles are equal.
   • Alternate Interior Angles are equal.
   • Co-interior Angles are supplementary.
   • Co-exterior Angles are supplementary.
   • Corresponding Angles are equal.
   • Vertically Opposite Angles are equal.

4. An angle is formed when two rays intersect at a point.

   • Supplementary Angles - Adjacent Angles which add up to be 180°
   • Complementary Angles - Adjacent Angles which add up to be 90°
   • Adjacent Angles - Angles which have a common vertex and a common arm with both the uncommon arms on either sides.
