### 1.1 Building Blocks

1. 1. Geometry Warm Up: Define in notes -Reflectional symmetry -Rotational Symmetry -Bilateral Symmetry ALSO: Put equation in slope intercept form. Identify slope and y intercept.
2. 2. 1.1 Building Blocks of Geometry pg. 28 to 34 Point- How do you name a point?
3. 3. Line- How do you name a line?
4. 4. Plane- How do you name a plane?
5. 5. Let's try the Investigation on page 29. What examples do you see of... Points Lines Planes Don't forget to raise your hand!
6. 6. Now quietly take a few minutes and define the bold words on pg. 30-32 DON'T forget to make an illustration of each Know how to name them (symbolic notation) ! Which points are collinear? Which are coplanar?
7. 7. Collinear- Coplanar- Line Segment- What is the difference between AB, AB, and mAB?
8. 8. Congruent Segments- What does it mean to have congruent segments? How do you write it? How do you indicate it on a figure? see page 31!
9. 9. Midpoint- Bisect- So can you bisect a line?
10. 10. Try example pg. 32 Yes the solution is underneath it--try not to look at it SEE if you can do it yourself first!
11. 11. Ray- Does order matter when naming a ray? What about a line? What about a line segment?
12. 12. Now you try it.... Pg. 33 # 1-27 odd Work quietly DO IT yourself first-- If that doesn't work, ask 3 before you ask me!
