  1. Vocabulary Nothing new! You learned this in Algebra I. Distance on the Coordinate Plane What You'll Learn You will learn to find the ______________________on the coordinate plane. distance between two points

  2. C(2, 3) A(-3, 1) B(2, 1) y 29 ≈ 5.4 What is the measure of AC? x Distance on the Coordinate Plane Hands-On! 1) On grid paper, graph A(-3, 1) and C(2, 3). 2) Draw a horizontal segment from A and a vertical segment from C. 3) Label the intersection B and find the coordinates of B. QUESTIONS: (x2 – x1) = 5 What is the measure of the distance between A and B? (y2 – y1) = 2 What is the measure of the distance between B and C? right triangle What kind of triangle is ΔABC? If AB and BC are known, what theorem can be used to find AC? Pythagorean Theorem

  3. y B(x2, y2) d A(x1, y1) x Distance on the Coordinate Plane then d =

  4. Find the distance between each pair of points.Round to the nearest tenth, if necessary. 5 4.5
