Unformatted text preview: 13-6 The Distance Formula
A) Distance Formula a. The distance between the points and is i. b. Proof
c. 2 points What are the coordinates of our new point, C? What are the distances of AC and BC? Now we can find AB.... d. Remember for 3 dimensions our formula is i. B) We can use the distance formula for multiple situations a. Proving a triangle is isosceles or equilateral b. Betweeness c. Perimeter d. Length of the median/altitude e. Diagonal of a solid C) examples a. Find the perimeter of the triangle with vertices (2,0), (4,3), (7,-2) b. Find the values of x such that the triangle whose vertices are (- 3,0), (0,3) and (-x,x) is equilateral c. Find the distance between A(2,-3,2) and B(4,2,-2) ...
