Guided Notes
3 key concepts
- 1
To find the distance between two points, create a right triangle where the line connecting the points is the hypotenuse.
- 2
The length of the legs of the triangle can be determined by the difference in the x-coordinates and y-coordinates of the points.
- 3
Using the Pythagorean theorem, a² + b² = c², where c is the distance between the two points, we find that the distance, c, is equal to the square root of 85.
