Angle problem on Dec SAT

<p>Did anyone end up figuring out the right answer to this one? I definitely think that many people got tripped up on this one.</p>

<p>it is definitely one
1 and 3 are corresponding angles and therefore are equal</p>

<p>was this domestic satuday SAT?
because i didn't get it</p>

<p>Can someone post the question?
I heard it was very difficult. I didn't get it on my test but I wanna see if I can solve it.</p>

<p>its only and just angle One...its THE ONE</p>

<p>i got two angles problems
but that's because i got an experimental math section meh</p>

<p>it...was something like [url=<a href="http://aviary.com/apps/webv2/creation.aspx?u=joshma&seoname=math!%5D%5Bimg%5Dhttp://rookeryiis1.viary.com/storage/647500/647721_46c9_625x625.jpg%5B/img%5D%5B/url"&gt;http://aviary.com/apps/webv2/creation.aspx?u=joshma&seoname=math!]

<p>heh. i made this rather quickly. it went along the lines of AC and AD are perpendicular, DC and AB are perpendicular, and EF is parallel to AD.</p>

<p>which angles must be equal to angle 4?</p>

<p>i only remember two answer choices:
- angle 1
- angles 1 and 2</p>

<p>(someone correct me if the image if i forgot something / remembered it wrong)</p>

<p>they didnt give you angle 3, 3 was in place of 4, and 4 was in place of 5</p>

<p>The choices were A)1 only, B) 2 only, C) 4 only, D) 1 and 2, E) 2 and 4</p>

<p>I got A, 1 only.</p>

<p>I'm pretty certain teh answer was A, 1 only, which is what I put</p>

<p>Explanation:</p>

<p>as seen in the diagram, it cant be 2 only or 4 only because they are corresponding angles and are therefore congruent to each other, so b and c are out of the question</p>

<p>it also cant be 1 and 2 because in order for it to be 2 it also has to be 4, and 1,2,4 is not an answer</p>

<p>therefore the only two possible answers are 1 only or 2,4</p>

<p>but it ends up only being 1 because when you draw the diagram with a different proportion than the one they give you, you see that angle 1 and angle 3 remain the same.</p>

<p>lol they drew a pretty good diagram to try to fool you xD</p>

<p>Angle 1 ONLY.</p>

<p>damn it!! there goes 800 math. i put 2 since it made sense at the time. </p>

<p>wait!!! hold up! looking at the diagram, i DEFINTIELY put the angle on the bottom left. but are you sure it was angle 1? Is that numbering right?</p>

<p>btw, the reasoning i used was a bit different. see the triangle on the left? i got angle 3 to equal the top left corner of the triangle, and since that triangle was a right triangle, then the other angle would be the complement. As a result, the angle complimentary to that angle (1) would be the same as 3. But I really hope I put the right answer. Like omg</p>

<p>thats exactly wat i did nbafan... but i ended up thinking angle 1 and 2 were equal as well so put 1 and 2 -_-</p>

<p>ouch dude. thats tough. hopefuly the scale is good for this and one wrong is like 780</p>
