1. Introduction to the Foot of perpendicular from a point to a line

Welcome to the realm of geometry, where we'll unravel the concept of finding the foot of the perpendicular from a point to a line. This geometric operation is crucial in understanding distances and relationships between points and lines. In this guide, we'll explore the definition, formula, and practical applications of finding the foot of the perpendicular, equipping you with the tools to tackle geometric problems effectively.
Definition\bold{Definition}
The foot of the perpendicular from a point to a line is the point on the line that forms a right angle (90 degrees) with the given point. It represents the shortest distance between the end and the line, creating a perpendicular line segment.

2. What is the Formulae used?

To find the foot of the perpendicular from a point (h, k) from a point (p, q) to a line ax + by + c = 0
we use the formula derived from the concept of perpendicular distance from a point to a line:
hpa=kqb=(ap+bq+c)(a2+b2)\frac{h - p}{a} = \frac{k - q}{b} = \frac{-(ap + bq + c)}{(a^2 + b^2)}

3. How do I calculate the Foot of the perpendicular from a point to a line?

Identify the point and equation of the line in general standard form.
Plug these values into the formula and obtain the coordinates of the foot of perpendicular.
