Quiz: Distance in the Coordinate Plane (V2)

You can use this resource if you need to.

How it works ?

For the two ordered pairs (x, y) displayed, calculate the following:

1) Absolute value of the RISE between those two points

2) Absolute value of the RUN between those two points

Then,

3) Use the Pythagorean Theorem to determine the distance between both points. Enter an EXACT ANSWER in the Exact Distance input box. Simply type “SQRT(143)” (without the ” “) for the square root of 143.

For any value you enter correctly, this GeoGebra applet will indicate this to you.

For help visualizing the right triangle formed, see the 2nd GeoGebra applet (below this one). You can reposition the 2 LARGE POINTS anywhere you’d like!
