9/11/15 CC Geometry UNIT: Tools of Geometry LESSON: 1.1b – Linear Measure and Distance MAIN IDEA: Students will be able to use information to determine the distance between two points and lengths of segments. HOMEWORK: Worksheet 1.1b Do Now: Solve for the missing sides of the two triangles below. 1) 2)

Segments and Rays A segment is a line that has two endpoints. Unlike a line, a segment can be measured. A segment is named using its two endpoints. A ray is a line that has only one endpoint. A ray is named by its one endpoint and one other point on the ray.

Betweenness

Distance in the Coordinate Plane

Distance Formula (Coordinate Plane)

Use the diagrams and coordinates to find the length of each segment: 1) 2) 3) A = (0, 0), B = (3, 4) 4) C = (-4, 9), D = (-5, 3) 5) E = (3, 4), F = (7, 2)
