Question

What is the distance between points P(10, 7) and Q(1, 8)?

Answer 1

You have two ways:
1) a formula.
2) an intuitive way using right triangles and Pythagorean Theorem.

Answer 2

Do you know the distance formula?

Answer 3

\[Distance = {\sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}} \]

Answer 4

Or the intuitive approach is,

Answer 5

Points are close enough together to make it an easy picture to draw and use Pythagoras' theorem.
