Could someone 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!

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

What mathematical statement is missing ? ? the answer is b
