Distance between points

To find the distance between the two points, we first need to form a right triangle!

Click on the third box (line with one point on each end) and click segment. Start at (5,5) and place a new point on the coordinate plane. Connect it to (20, 15). This should make a right triangle

1. Identify the coordinates of the third vertex. And, find the horizontal distance (difference in x – coordinates) and the vertical distance (difference in y – coordinates).

2. Find the distance from (5,5) and (20,15). Include units

3. Suppose you picked a different vertex that still makes the triangle a right triangle. Predict if the distance from (5,5) and (20,15) will stay the same or change? Verify your answer by picking the other vertex and using it to find the distance.
