2 cards from this section. Quick, good the night before a test.
Calculate the distance between the points P1(0, 0) and P2(3, 4).
Use the Distance Formula: d = √((x2 - x1)² + (y2 - y1)²)
What is the distance between P1(1, 1) and P2(1, 4)?
Notice the x-coordinates are the same.
What is the Distance Formula?
Recall how we derived it from the Pythagorean theorem.
True or False: The distance between two points can be negative.
Think about what distance measures.
Two points, P1(2, -3) and P2(3, 4), are given. Calculate the distance and interpret this result.
Be careful with the signs and squares!
If P1(1, 1) and P2(8, 8), how can this help in determining the coordinates of a triangle's vertices? Estimate the location.
In a triangle, the relationship between points often matters; use this distance.
