Lines in GeometryOnline version Test your knowledge of geometric concepts by correctly ordering different types of lines based on their relationships. by lyssa daud 1 Parallel lines are have the same slope. two or more straight lines They are always the same distance apart and that never meet, 2 If two lines are parallel they have the same slope. Line 1 : y = m₁x + c Line 2 : y= m₂ x + c ∴m₁ = m₂ 3 Perpendicular lines are two straight lines that cross each other at a 90-degree angle (a right angle). 4 If two lines are perpendicular Line 2 : y= m₂ x + c m₁⋅m₂ = -1 Line 1 : y = m₁x + c
