Distance and Direction Reasoning Formulas

This chapter deals with the linear distance and direction between two points in two dimensional planes. To solve the problems based on distance and direction the sense of direction and standard Trigonometrical ratios are important.

1. The angle and direction
Angle and Direction formula 01

2. The standard Trigonometrical ratio table
Distance and Direction formula 02

3. In any right angled triangle, +=
Distance and Direction formula 03
