Look at triangle ABC.
Coordinate grid shows negative 5 to positive 5 on the x axis and y axis at intervals of 1. A triangle ABC is shown with A at ordered pair 4, 5, B at ordered pair 1, 2, and C at ordered pair 4, 2.
What is the length of side AB of the triangle? (1 point)
Square root of 6
3
Square root of 18

    AC is vertical, they have the same x
BC is horizontal, they have the same y
so just counting , AC = 3 , BC = 3
so AB^2 = 3^2 + 3^2 = 18
AB = √18 = 3√2
I see that choice
