Unit 9 Review  

I am so sorry!  I thought this had already posted.  Here are the links to the videos we watched on Friday and Monday.  You really only need to know the names of the Platonic Solids.  The video is 17 minutes long, but you really just need the names....

Here is a picture of the platonic solids: tetrahedron, hexahedron (cube), octohedron, Dodecahedron, Icosohedron


For Cross Sections (from Monday)




For Platonic Solids (Friday)  The names are



Answers to the review

1 and 16.  You really only need to know rectangle, triangle, trapezoid

2.  A pyramid is not curved, so you can't get a curved 2D shape.

3.  parabola, triangle, circle

4.  hexagonal prism

5.  hexagons

6.  parallelograms/rectangles/squares.  You cannot assume they are squares or rectangles.  They are parallelograms.

7.  rectangular pyramid

8.  1, rectangle

9.  4, triangles

10.  A face of a 3D figure that connects the two bases (in a prism) or a base and an apex point (in a pyramid).  They are the "sides."

11.  9 cubes

12.  7 cubes.  One could float/attach to the side of another cube.

13.  Right prism means that you will have rectangles as the lateral faces.  The axis is perpendicular to the base.

14.  4 right angles in a rectangle so 4x 5 = 20

15.  mad, crazy, happy

16.  see #1

17.  Remember, odd number of vertices means it is a pyramid.  5-1apex point leaves 4 vertices, so rectangular pyramid.

18.  see #14

Pre-AP Test Review  

As previously stated, I have posted some videos to assist students in preparation for the test.  Please go to


You will need to sign in as a student using Class Code PTPREPD

Helpful hints to finish this test tomorrow.  When you are doing composite area, you have to look at the big picture.  For the most part, the test questions require you to subtract an area from a bigger area.  Plan the solution.  Rectangle - circle, .25 circle and .5 circle.  Make a plan to find the area and answer the question.

I have tutoring today after school and tomorrow before school.

Happy studying!

Test tomorrow   

I sent the answers via email to parents.  I also have two videos posted at educreations.com   Sign up as student and use the code PTPREPD to find my videos.
