2-5: Perpendicular Lines

Perpendicular lines: 2 lines that intersect to form right angles (90 degree angles)

Theorem 2-4: If 2 lines are perpendicular, then they form congruent adjacent angles

Theorem 2-5: if two lines form congruent adjacent angles, then the lines are perpendicular

Mr. Muir’s Theorem: Perpendicular Lines form Congruent adjacent right angles

Theorem 2-6: If the exterior sides of adjacent acute angles are perpendicular, then the angles are complementary
