Geometry Warm Up:

Define in notes-Reflectional symmetry-Rotational Symmetry-Bilateral Symmetry

ALSO:Put equation in slope intercept form.Identify slope and y intercept.

Point-

How do you name a point?

1.1 Building Blocks of Geometry pg. 28 to 34

Line-

How do you name a line?

Plane-

How do you name a plane?

Let's try the Investigation on page 29.

What examples do you see of...

Points

Lines

Planes

Don't forget to raise your hand!

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?

Collinear-

Coplanar-

Line Segment-

What is the difference between AB, AB, and mAB?

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!

Midpoint-

Bisect-

So can you bisect a line?

Try example pg. 32Yes the solution is underneath it--try not to look at itSEE if you can do it yourself first!

Ray-

Does order matter when naming a ray?

What about a line?

What about a line segment?

Now you try it....Pg. 33 # 1-27 oddWork quietlyDO IT yourself first--

If that doesn't work, ask 3 before you ask me!
