Geometry Regents June 2017

Did you get 0.6 for the cube root question

I was never taught cube roots in either algebra 1 or geometry. But yeah, I got .6 after I found the button somewhere in my calculator. I didn’t like that question…It wasn’t a terrible question but no one in my school learned how to do cube roots so I thought it was unfair. Same with cavalieri’s principle, at least for the kids in regents classes. My honors class mentioned it once so I sort of knew what it was referring to, but I obviously didn’t study it closely thinking it would be on the regents.

It was definitely 210 mph. You had to subtract the two distances, not add them because the plane was flying towards her.

Ok I got 36 because if you plugged in 36 for the angle you were solving for and found every angle in that quadrilateral that was inside the triangle it added to 360 degrees and in every quadrilateral the interior angles add to 360. If you got 54 it added to 556 or something not 360. Also I did this at first but it was incorrect, if two triangles have 1 side congruent it doesn’t mean that the opposite angle is also congruent, also the quadrilateral was not a parallelogram( it didn’t say opposite sides were congruent) so you couldn’t assume opposite angles were congruent. That’s how I got 36. If you plugged it in and solved for each angle in that quadrilateral it added to 360

The hypotensue dossnt measure distance. The hypotenuse would be the distance together with the height (not adding but compensating for height also). Distance is how far you are from something regarding the height that’s why u use the two legs and not the hypotenuse

OK FOR FREDAS QUESTION YOU GUYS ARENT REMEMBER WHAT IT SAID CORRECTLY. It said that she thinks it is gonna fly overhead, not that it already did. The plane is flying toward her which is why the angle of elevation is increasing closer to 90( 90 being directly overhead). Does that clear it up?

Unless for the question where I got 36… did it say two sides of that quadrilateral inside the triangle has parallel sides?

I remember it said there was a midsegment, so at least one side was parallel. That’s how you could start solving through corresponding angles. It wasn’t a parallelogram though. I thought I solved it right and got 54, but I guess I never checked back into the quadrilateral to see. I might be getting this confused with another angle question that I got 70 for, not really sure at this point.

Wait, Real quick question guys… I might have answered the Short Answer part of the test in pencil, and when I handed it to my proctor she didn’t say anything. Any idea If my test won’t be graded because it was supposed to be in pen, or…?

What did you guys get on the mc question that asked what shape reflects over its sides or something like that, I put down square I think

@SuicidalSith it was the octagon because square only had 2, triangle had 3, and rectangle had 1 reflection that could land on them self

@somatropin thanks

I picked octagon too but I think that’s wrong. Octagon has 8 lines of reflection. A square can be reflected 4 ways - don’t forget about diagonally!

What did you guys get for the multiple choice dilation question with the 4 roman numerals

@Section only answers in pen are graded but i think the proctor has to tell you if you wrote anything in pencil so i’m sure you’re fine

It’s a square

It was square. Square has 4 lines of symmetry, so it can be reflected on to it self 4 different ways. An octagon has 8 lines of symmetry, so the answer was square

It was 54, because it said the lines are in proportions, means they were parallel. So you had to do the corresponding angles. If you did that you would get the angle f was 54

Yea but EVERYTHING was answered in Pencil. It wasn’t until I got home and my friend told me that she got lucky that her proctor told her to rewrite everything in pen or else it wouldn’t be graded, and that’s when it hit me that I’ve done goofed up. I forgot to switch to pen and my proctor didn’t remind me that short answer was to be in pen.

@Section I’m sure they’ll grade it. I did that for my Biology exam (all short answer in pencil) and I asked a proctor and she said it was fine.
