Prove and apply theorems about lines and angles.
• Include multi-step proofs and algebraic problems built upon these
concepts.
• Examples of theorems include but are not limited to:
o Vertical angles are congruent.
o If two parallel lines are cut by a transversal, then the
alternate interior angles are congruent.
o The points on a perpendicular bisector are equidistant
from the endpoints of the line segment. |
