Question

Could someone help me with this? You have to find the distance between each pair of points. I prefer to use the DSAR method, but I can convert if needed!

Answer 1

A(-4,7) B(6,2) C(3,-2)
The distance between 2 points A(x₁ , y₁) and B(x₂, y₂) is as follows:

(AB)² = (x₂ - x₁)² + (y₂ - y₁)² And
AB = √[(x₂ - x₁)² + (y₂ - y₁)²]

AB = √[(6+4)² + (2-7)²] = √[(10)² + (-5)²] and AB = √125 = 5√5 or 11.18.

Now follow the same logic to solve BC and AC. If you find any difficulty, do let me know
