distance formula of triangle. The very essence of the Distance Formula is to calculate the length of the hypotenuse of the right triangle which is represented by the letter c. Distance x 2 x 1 2 y 2 y 1 2.

A median is a line segment joining a vertex to a midpoint to the opposite side of the triangle. The Distance Formula itself is actually derived from the Pythagorean Theorem which is a2 b2 c2 where c is the longest side of a right triangle also known as the hypotenuse and a and b are the other shorter sides known as the legs of a right triangle. A2 b2 2 ab c2 2 ab.
The length of the hypotenuse is the distance between the two points.
But this is equal to the square formed by the triangles line 1. Given the two points x1 y1 and x2 y2 the distance d between these points is given by the formula. Use the distance formula to find the length of two of the sides. D x 2 - x 1 2 y 2 - y 1 2 The expression x 2 - x 1 is read as the change in x and y 2 - y 1 is the change in y.
