SAT Geometry: Everything You Need To Know

by Craig · 18 comments

I have broken this lesson into the three parts you must know:

2D Shapes – 3D Shapes – 2D Coordinate Geometry

With this in mind, I attempted to make these videos as short and as easy as possible. These three videos combined are a little more than 1 hour, and they give all the knowledge you NEED to dominate your SAT.

2D SHAPES

The most important 2D shapes on the test are parallelograms (squares and rectangles, mostly), triangles and circles. I don’t know about you, but I freakin’ LOVE triangles. I don’t know why, so I spend a lot of time with them.

Awesome vid, huh? I’m not perfect at those screen caps, and my Bamboo pen is not 100% perfect, but I’m trying.

I made this PDF template of the formulas and shapes, just for you. Download here

3D Shapes

3D shapes come in many SHAPES AND SIZES, haha, but the idea here is to find the surface area and the volume, and to also find some diagonals. Other than that, you don’t see much 3D on the SAT.

Remember, I am here to give you an efficient way to succeed, not to give you EVERY POSSIBLE OPTION. If you want every possibility, I have a link to a great SAT course that is already made. (Note: I will probably put together a sat course for you, but until it’s ready, I will link to a friend of mine who has an awesome course. Hop to the end for me info.)

Whoa, I like those colors! Next time I will try and use FOUR colors.

Coordinate Geometry

Coordinate planes are awesome. I used to be a philosopher, so I used to go all Descartes-crazy. So, you get some philoso-speak in this last video.

Whew, what a day! If you watched all of these at one time, good on you! If you didn’t, smart kid. Make sure you bookmark because I have all kinds of updates and goodies coming in the next few months.

Outside of Craig Resources:

Note: These aren’t necessarily free, but they ARE awesome, and I fully support them:

(1) SAT Official Guide:

Look, not prep is complete without the damn book. Buy this blue book whenever you can. I love amazon, because they are the bees-knees (whatever, I’m old!), but you can just go to your local bookstore and buy one yourself, if you hate the post.

(2) SAT Math Video Series:

Look, this is a pretty amazing product. Now, since I am not 100% handsome, I make these videos on screen flow because I think you want to see the work, not my desk or my face, but Soren goes ahead and records himself solving math problems. Every possible math problem on the SAT is covered in this course. I am developing my own course, but until it comes out, I will highly recommend Soren’s course. Also, if you go halfway through his sales-y page, you can see a free coordinate geometry video, which is about as good as mine ;)

If you liked this, do me a solid and share with your friends.

    Hi Nisha!

    Thanks so much for the comment! I work hard to make these videos as good as possible. I know you are taking your test this Saturday, but if you stick around and take it in the future, I’ll make sure to do one or two algebra videos this christmas!

    hey man i was watching your first video of geometry and in one on the triangle segments of the whole video you were finding the heght of a special equalateral triangle and you got 5 square root 3 in one half of the triangle and i was wondering,how did you get that part of the whole equation?

  • A

    Dude, you rock!

  • craiggonzales

    Oh shucks! Thanks man. I hope it was awesome.

  • B

    You’re amazing. Thank you!

    Dude, That’s awesome! thanks.

    Thanks for doing this! The videos were definitely helpful and a good review :D

    I know that your site is mostly for SAT prep and such, but if you’re looking for more topics to make videos on, I would appreciate some pre-calculus. I’m finding it hard to find people to answer my questions…
    Your videos are awesome and engaging; I’m glad I found this site!
