Geometry Unit 4 EOC Practice
|
I'm horrible at Geometry. Absolutely horrible. Because of that I failed my first semester and thus need to take a one session of night school to make it up. So I'm really trying to buckle down, but I can't seem to figure out how to do even the first problem. I don't even know what chapter it is in the book. If you can help me with it, or at least give me a chapter number or site for help, I'd be grateful. The problem shows a quadrilateral with two cross lines inside. At the top left hand corner, Angle B shows to be 53 degrees; the right angle where the cross intersects shows to be 115 degrees. The question is 'Using the figure above, what is the measurement of angle BAC?

I never liked geometry... and it might help if you could link people to a picture so they know what exactly they are dealing with. |

"right angle where the cross intersects shows to be 115 degrees" this makes no sense. a right angle is, by definition, 90 degrees. |

Agreed with DeWayne Mann. I think S. C. Fayth was assuming a right angle from the diagram, though. Which would not be allowed. Not to be mean, but I can understand why you failed. Perhaps you should start at the beginning of the book and start learning all the vocabulary and theorems. Otherwise you will fail again. Just put a bit of effort into it. It may not be the best sentence gramatically, but you can't spell GEOMETRY without ME TRY. |

If you're not the math kind of person (left-brained), then you must be the english kind of person (right-brained)! And you know what is a good idea to use that statement to your advantage? Treat your Geometry class as an English class, to a degree. I'm going to make a fair assumption here that English is one of your top subjects and memorizing vocabulary and enunciating them to others is not a problem. With that said, I think you can do the same in a math class. At the beginning of each chapter, you might want to create notecards and memorize key terms. Like a right angle: one side his the word "right angle"; the other side has the answer and maybe a diagram to improve that imagery "90 degrees". Also, touching on that point, if you do decide to use notecards, I have discovered that pictures really help you remember. It is a technique one of my old English teachers used to use. Sometimes, instead of blatantly leaving the answer on the back of a notecard, sparingly jot down hint words, phrases, or pictures to give you that mental image of what you're talking about. That can prove especially important on tests too. Like, if you see a formula for finding slope, you could have thought of a drawing you made earlier in your practice. That leads me to my next point: no matter how difficult and impossible Geometry may be, it is not impossible for anyone. If it was impossible, then there wouldn't be any 'A' students. But there is. So if they can do it, you can do it. I know some people are just naturally talented in math, others who just study a lot, and others who just aren't good at all. But, like most people, to perform well in anything requires training. No one in the class is going to nail the test the first time around. That's why they're in the class! To learn! They're in the same boat as you, they just may grasp it a little faster. It's good, though, that you have recognized your faults. Hopefully you can take some of my strategies and apply them to your situation. But remember: PRACTICE - PRACTICE - PRACTICE Do not study for an exam the night before and expect, by some divine intervention, that God is just going to hand you a silver platter with a grade 'A' on it. You gotta work for it man. It ain't over till the fat lady sings. |

My bad, I didn't notice how oddly I had phrased the picture description until everyone commented it. Its supposed to be an angle to the right of where the cross intersecets is, shows to be 115 degrees. I figured out the problem, after a lot of help from a friend, but I'm still very very open to any studying tips. And you pretty much hit the nail on the hammer, Staryu. I'm definitely an english sort of person. I had thought of trying to treat my math classes like they were a "different form of english" before, but was never quite sure where to approach it. I think I'm going to try some of those hints. Just start going through the text book and gradually teaching myself the math again. The EOC isn't for a while now, about a month I think, so I might have plenty of time to study enough to make me profficient. Thanks a lot for the suggestions everyone. |

Okay I had trouble...a lot of trouble with Geometry earlier this year, believe me. My parents hired a math tutor for me earlier this year and now I'm doing great...I don't even think I need to see him anymore...anyway...here are some tips for geom: 1. Talk to your parents...see if they can find a math tutor for you. 2. Stay after school once in a while to talk to your teacher if you don't understand something. Don't be afraid to ask questions during class, either. 3. Learn the theorems, postulates, definitions, EVERYTHING and MEMORIZE THEM. Make flashcards of all them. Normally, you can find a list of them in the back of your book. Once you learn those, computation and proofs will become easier I swear. 4. If you're doing a proof or computation problem and you come to something you have no clue what you can do, try to think of what makes sense...like I always forget that in a parallelogram, the top right angle is congruent to the lower left and the upper left is congruent to the lower right...but then I just try to remember the theorem and think of what would make sense...it wouldn't be some random, impossible to get number...you just gotta apply what you think you know... Good luck in the class. Believe me, I understand the troubles in geometry... |
