I haven't seen the test, so I'm not sure what you are asking.<br /><br />"C is the sum of both sides" doesn't make sense in a triangle. One side can't be as long as two other sides. <br /><br />As for the proof:<br />A rhombus has 4 congruent sides and two pairs of parallel sides. Distance formula will give you the length of each side. If the consecutive sides are not congruent than the figure cannot be a rhombus.<br /><br />A parallelogram just needs to have to pairs of parallel sides. Parallel lines have the same slope. Find the four slopes. If the slopes of the opposite sides are the same, then the quadrilateral is a parallelogram.(x, why?)https://www.blogger.com/profile/17499160002806879025noreply@blogger.comtag:blogger.com,1999:blog-28172905.post-81453181435262245012013-08-13T20:57:59.351-04:002013-08-13T20:57:59.351-04:00How did you find the side of c if it said that A w...How did you find the side of c if it said that A was -15 less than B and C was 2 times the side of A and C is the sum of both sides? And how to prove the sideway triangle with the line going down the center? And the last question: where it asked to prove it is not a rhombus, prove its a parallelogram.Alex384https://www.blogger.com/profile/09108235147156021280noreply@blogger.com
