To get ahead,You have to do extra!

Midpoint: point halfway between the endpoints of the segment.

Midpoint measure on the number line

Midpoint measure in a coordinate plane

Bisect: To cut into two equal parts

Segment bisector: Any segment, line, or plane that intersects a segment at its midpoint.

The bisectors of AB if point M bisects AB

RM, point M, MD , Plane N

c. How do we find measurements using collinearity andbetweenness of points?

Betweeness of Points

For any real numbers, say a and b, there is a numberbetween a and b so that a<n<b. n is between a and bOnly works if points are collinear. d. What is congruence and how can we use congruence to find measurements?Congruent - 2 segments having the same measureSame shape, same measure

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

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.

What is congruence and how can we use congruence to find measurements?Congruent - 2 segments having the same measure

Same shape, same measure Stronger than equality!!!!!

How do we show two line segments are congruent?

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

c. How do we find measurements using collinearity andbetweenness of points?

Betweeness of Points

For any real numbers, say a and b, there is a numberbetween a and b so that a<n<b. n is between a and bOnly works if points are collinear. See examples

Get into groups of two Group 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?
