18. Congruent - Same shape, same measure What are the congruent segments? How do we know they are congruent? How do we show they are congruent? Old Book pg 17#22-32 evens

21. 9/5/2013 Section 1.2 Objective: SWBAT measure segments. Fundamental Questions: a.What is a line segment? How do we label a line segment and show its measure? A part of a line that can be measured. It has two end points. b. What are ways to measure a line segment? Why is it important to consider precision in measuring? To measure a line segment use a measuring device such as a ruler or a compass (Construction). Precision deals with the accuracy of measurements.

23. Congruent - Same shape, same measure What are the congruent segments? How do we know they are congruent? How do we show they are congruent?

25. c. How do we find measurements using collinearity and betweenness of points? Betweeness of Points For any real numbers, say a and b, there is a number between a and b so that a<n<b. n is between a and b Only works if points are collinear.

30. Get into groups of twoGroup it Up! Materials: 2 toothpicks, index card, pen or pencil, tape. Write header info on your index card. Include both names. Step 1: Mark 4 collinear points on one toothpick. Step 2. Tape this toothpick to the index card. On the index card, label the four points, A, B, C, D. Mark a noncollinear point P on the index card. Step 3. The toothpick represents a part of a line. On the index card, how do we show that the tooth pick is a line? How many points are on a line? Label the line as line m. Step 4. What is a name of the line? How many different names are there for this line? Step 5. The index card is the plane. Name and label a plane M on your index card. How many points are needed to make a plane? What kind of points must they be? Step 6. With your second toothpick? Mark two points on this toothpick. This toothpick is called line n. One point is point G and the other is point H. Step 7. Punch a hole in the index card with the toothpick so that the toothpicks intersect at point B and point G. When two lines intersect, what do they form? Is line n contained in plane M? Are point B and point H, collinear? Are point H and point D collinear? More questions? Are points A, B, H and P coplanar? Why must we look at four points?
