Lesson: Equations of Parallel and Perpendicular Lines Mathematics

Students will be able to

• understand what parallel and perpendicular mean with respect to the gradient of lines,
• identify whether two given lines are parallel, perpendicular, or neither,
• find the equation of a line that is parallel to another given line,
• find the equation of a line that is perpendicular to another given line,
• identify types of quadrilateral shapes (e.g., trapezoids or squares) given the coordinates of the vertices by showing that the sides are parallel or perpendicular as required.
