Rainat2PM 0 Posted November 28, 2009 I was given: ray GB is perpendicular to ray GC prove: angle 1 and angle 3 are complementary[img][/img] Share this post Link to post Share on other sites
haha_13 0 Posted November 28, 2009 i know geometry is not that easy... but asking others do your homework is not right... sorry if i talk like a grandfather teaching his grandson a lesson... but how will you learn if you don't do ur own assignment? Share this post Link to post Share on other sites
xPink.Pixel.Princessx 0 Posted November 28, 2009 This makes no sence to me at all hehe. I was never good at geometry and never could get my head around it so i never tried. I would love to help you but i just cant...so sorry Share this post Link to post Share on other sites
lea75 0 Posted November 28, 2009 I have to agree with haha13 here... Maybe if anyone can help with how to solve this, and give a different example, then you can solve it yourself Share this post Link to post Share on other sites

Lucky Strike 0 Posted November 29, 2009 or simpler.. since ray GB is perpendicular to ray GC then the have a corner of 90 degrees... the straight line has 180 degrees.. so the other 2 are in total 90... that was it... Share this post Link to post Share on other sites
Lucky Strike 0 Posted November 29, 2009 sorry for the tonw of posts.. but at start a thought that you needed that 1 and 3 are equal and complememntary Share this post Link to post Share on other sites
