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