1. Building Blocks of Geometry Objective: Learn and apply the basic terms used throughout Geometry.

2. Points, Lines and Planes Points: No dimensions, no thickness, gives the location, represented by a dot, use a capital letter to label Line: 1 dimension, goes in opposite directions forever, goes through at least 2 points, name by using 2 points that are on the line and putting a line symbol above them Line Segment: Part of a line, has 2 endpoints, it can be measured, name using two points on the segment with a segment symbol above it Endpoints – points that start and end a segment

3. Con’t Ray: Part of a line, has one endpoint, goes in one direction forever, to name need to have endpoint first and then second point and put the ray symbol above Plane: Goes in 2 dimensions, think of coordinate system going on forever in 4 directions, draw it like a rectangle, need at least 3 points for a plane and named using a capital script letter usually written in the corner of the plane Space: Goes in 3 dimension, think of length, width and depth, a Kleenex box that continues to go on in every direction

4. Collinear and Coplanar Collinear: Need at least 3 points, all of them are on the same line Noncollinear: At least three points are not on the same line Coplanar: Needs at least 4 points, all of them are on the same plane, points should be noncollinear NonCoplanar: At least four points are not on the same plane, points should be noncollinear

5. More Terms Midpoint – a point that is the same distance from both of the endpoints, middle of the segment, making 2 congruent segments Bisect – to cut something in half, cut into congruent parts, the midpoint bisects a segment Know symbols for congruent – have same number of markers in the segment or angle

6. Example Name a line, ray, segment, collinear points, place, coplanar points

7. Example Given the picture name a line, ray, segment, state 3 points that are collinear

8. Objective: Learn and apply the basic terms used throughout Geometry. On a scale of 1 to 4 Do you fee we meet the objective for the day. If we did not meet the objective, what did we miss and how could I improve.
