Distance from a Point to a Line: Distance Formula
2015-11-25 14:56
This applet demonstrates the geometric derivation of the distance formula from a point to a line. By constructing lines, points, perpendicular segments, polygons, and angles, it visually illustrates using coordinate geometry to find the distance. Ideal for classroom teaching, it helps students understand the geometric meaning and algebraic derivation of the formula.
