**Do Now:**• Copy Down HW • Take out your notes and answer the following: • 2. Name the intersection of BAF and AGC. • 3. If two lines intersect, • what does their • intersection • form?**Ch. 1.2**Use Segments and Congruence 2 cards**Definition**A segment is made up of the line in between two points, excepts segments do not continue on forever. B A**Ruler Postulate**The distance between any two points is the absolute value of the difference of the corresponding numbers**Congruent Segments**Segments with the same length**Segment Addition Postulate**If 3 points, A, B and C are collinear and B is between A and C, then AB + BC = AC**Ex 1:Plot the points in a coordinate plane and determine**whether the line segments are congruent**Example 2: in the diagram, HE=12 miles, and HS=17 miles. How**long is ES? H E S**Example 3: In the diagram, SA=2x-1, AT=3x+4, and ST=10. Find**x then find the length of SA. T A S**Let’s Go Outside! Geometry Photo Scavenger Hunt**• In groups of two, you will go outside and find and take pictures of the following: • A segment between two points • Two intersecting lines • Two intersecting planes • A line intersecting a plane • Two lines that do not intersect • Two planes that do not intersect**Let’s Go Outside! Geometry Photo Scavenger Hunt**Once you take pictures of all the items on the list, send them to me in an email: joyk@villagechristian.org First two groups to send me an email with all items get a prize!**Exit Slip: In the diagram, the points A,B,C and D are**collinear. AD=60, AB=14, and BC=CD Find CD
