Math Basics: Midpoint, Parallel Lines, and Perpendicular Lines

The video tutorial covers three main topics: midpoints, parallel lines, and perpendicular lines. It begins with an explanation of how to calculate the midpoint between two points by averaging their coordinates. The tutorial then moves on to parallel lines, explaining that they have the same gradient and never intersect. It provides examples of equations for parallel lines and how to find specific points on them. Finally, the video discusses perpendicular lines, highlighting that their gradients are negative reciprocals of each other, and demonstrates how to calculate these gradients.
