Parallel and Perpendicular Lines--Unit 5A(Chapter 5)
Standard(s):
CC.4.G.1 Draw and identify lines and angles, and classify shapes by properties of their lines and
angles. Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify
these in two-dimensional figures.
CC.9-12.G.CO.9 Prove geometric theorems. Prove theorems about lines and angles. Theorems include: vertical angles
are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles
are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment’s
endpoints.
