LESSON Content Standards G.CO.1 Know precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc. G.CO.12 Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.). Mathematical Practices 2 Reason abstractly and quantitatively. 7 Look for and make use of structure.

LESSON Then/Now You graphed points on the coordinate plane. Find the distance between two points. Find the midpoint of a segment.

LESSON Vocabulary distance midpoint

LESSON 1.3 Distance and Midpoint Objective: 1.Find the distance between two points. 2.Find the midpoint of a segment. Vocabulary: Distance, midpoint

LESSON distance: a part of a line that consists of two endpoints and all the points in between those endpoints – also called a segment.

LESSON If P(x 1, y 1 ) and Q(x 2, y 2 ) are any two points, then the distance between them can be found with the formula.

LESSON Find the distance between points A and B. A(-5, 3) B(7, 8)

LESSON Find the midpoint M of a segment with endpoints F(4, 12) and G(8, 6). M(6, 9)

LESSON Answer: (–3, 3)

LESSON Find the coordinates of R if N (8, –3) is the midpoint of RS and S has coordinates (–1, 5). Cool Tip #4: Endpoint (A, B) Midpoint (C, D) Endpoint (?, ?)
