Lan used the Pythagorean Theorem to find the distance between two points as follows, a² + b² = c²
(11 - 2)² + (3 – 15)2 = c²
92 + (-12)2 = c²
81 +144 = c2
225 = c2
C = 15
Which of these pairs of points could he have been finding the distance between?

you already gave the answer

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property
