Finish learning geometry in 20 days. Tips?

Question

I'm on page 375 in the textbook, only 250 pages to go, which is only 5 more chapters. Ive been taking notes on everything important in a notebook, and recently went through it and dog tagged all of the pages that I needed to study more(ones with important equations/theorems)

The last five chapters seem to be a lot more complicated then the first nine, so do you lovely people have any tips you could share with me? Also, what are the more important things I should be learning?

Im sad to say I put off learning geometry until halfway into the summer, so Ive been going through a chapter every three days. I learn it, then forget it. I have to take the geometry final at the beginning of September, so I really need to cram.

Any tips/ helpful sites/ anything at all would be very appreciated!

Im going into 10th grade if anyone is wondering, and I got an A in Algebra last year.

Sorry if this is in the wrong catagory, I didnt know where to put it!

Answer 1

I don't know which book you are using, so some of this may not make sense. If your class is taught in the same or similar order as the one I teach, then here is my advice:

Emphasize the rules of Right Triangle Trigonometry (sine, cosine and tangent). This topic is critical for future math success...it comes back again and again. One of trigo's best friends is the Pythagorean Theorem...but if you got an A in Algebra, you already know it.

Special Right Triangles...the 45-45-90 (isosceles right triangle) and the 30-60-90 right triangle (an equilateral triangle cut in half)...and their properties. They come back again when you get to meet the Unit Circle.

Similarity...if only for the practice in using ratios.

The Triangle Inequality Theorem. It says that the sum the lengths of any two sides of a triangle must be larger than the third side, or it is not a triangle. A simple thing...but if you know it, you will save yourself some pain later.

Those are the big ones for the future. Unfortunately, if your final is a multiple choice final, the easiest questions to ask are from the properites of quadrilaterals and the properties of circles. There is probably a chapter for each of those.

I hope that helps some...good luck!
