If the triangles are congruent EF = AB. You can use the distance formula/Pythagorean theorem to find the distance between (0,2) and (2,4)

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

How would I be able to solve using that equation. I'm confused

Sorry my power went out Your points are (x, y). Let (0, 2) be ($$(x_1,y_1)$$ and let (2,4) be $$(x_2,y_2)$$. Then plug the numbers into the formula.

$d=\sqrt{(2-0)^2+(4-2)^2}$
