mom31257 Posted March 3, 2016 Share Posted March 3, 2016 Can you help me help a friend? She sent me a picture from lesson 6.4 and is having trouble figuring most of the angles. Honestly, I am, too. It's got an angle in the top left that is 76 and one right below it that is 94, if that helps you find it. Finding angles a, b, and c are easy: 86, 86, and 60 respectively. The lesson was over kites, but the only kite shaped part doesn't have any pairs of congruent sides. What are we missing on figuring out the rest? I haven't done any geometry in quite some time. I am getting this book next year! Quote Link to comment Share on other sites More sharing options...
mom31257 Posted April 4, 2016 Author Share Posted April 4, 2016 Anyone using this currently? I have the book now and it is #2 on page 101. What am I not seeing? Quote Link to comment Share on other sites More sharing options...
almondbutterandjelly Posted April 4, 2016 Share Posted April 4, 2016 Are there any triangles in the diagram? Don't the angles of a triangle all add up to 180? Quote Link to comment Share on other sites More sharing options...
mom31257 Posted April 4, 2016 Author Share Posted April 4, 2016 I think you can see you the picture here. https://goo.gl/photos/nrKWq5My5nChk4bD8 Quote Link to comment Share on other sites More sharing options...
Miss Tick Posted April 4, 2016 Share Posted April 4, 2016 (edited) I'm looking at it and here is something: 1. There is a right angle in the middle (90) 2. There is a 120 at the bottom. 3. k is the base angle of an isosceles triangle, so the other base angle also equals k. 4. The vertical angle of b is also going to be 86. Those four angles form a quadrilateral, so: 90 + 120 + k + 86 = 360 Therefore, k = 64 Edited April 4, 2016 by SusanC 1 Quote Link to comment Share on other sites More sharing options...

I'll see if it helps me figure out some of the others. 1 Quote Link to comment Share on other sites More sharing options...
Miss Tick Posted April 4, 2016 Share Posted April 4, 2016 (edited) From there, I thought the others all looked pretty straightforward, but post if you get stuck! I finally feel like I accomplished something today. :-) Edited April 4, 2016 by SusanC 1 Quote Link to comment Share on other sites More sharing options...
mom31257 Posted April 4, 2016 Author Share Posted April 4, 2016 Thanks! I was able to figure out all the rest. Sometimes you can't see the forest for the trees! Quote Link to comment Share on other sites More sharing options...
