🔳Parallel lines do not intersect and have the same slope.
⊥Perpendicular lines intersect at right angles and have slopes that are negative reciprocals.
↔️A transversal line intersects two parallel lines, creating interior and exterior angles.
≅Corresponding angles are congruent, both located on the same side of the transversal.
θComplementary angles add up to 90°, while supplementary angles add up to 180°.
What are parallel lines?
—Parallel lines are lines in the same plane that never intersect and have the same slope.
How do perpendicular lines interact?
—Perpendicular lines intersect at right angles and have slopes that are negative reciprocals.
What are interior and exterior angles?
—Interior angles are between two parallel lines, while exterior angles are outside the two lines.
What are corresponding angles?
—Corresponding angles are congruent angles on the same side of a transversal.
What is the difference between complementary and supplementary angles?
—Complementary angles add up to 90°, while supplementary angles add up to 180°.
