Do Now – Geometry Take your seats and solve the following problem Use the figure to answer the questions. a) The flat surfaces of the pyramid are called faces. Name the five planes that contain the faces of the pyramid. b) Name three lines that intersect at B. c) Are points A,D, P, and C coplanar?

1.4 Finding the Measure of Segments What is a line segment? It is a part of a line that consists of two endpoints and all the points between them. A B W T D S R

Measurements on a Number Line How do you find the distance from one point to another on a number line?? Two ways… “Bigger number” – “Smaller number” Let’s try a few examples

The Distance Formula What is the formula? When do you use it? -Use it to find the length of a line segment on the coordinate grid.

1.4- Distance Formula Example #1: Find WY. A

1-4 Distance Formula Example #2: Find AX. A
