Special Triangles

Teisha, Angie, and Beth

Given an isoceles triangle ABC as shown with angles of 20, 80, and 80. Segments CK abd BL are drawn as shown so as to divide the base angles 30/50 and 20/60.

What is the measure of the angle KLB?

We can extend the segment KC to make the line KC and do likewise with segments KL and BL. This will yield the following picture and then we can begin to find angle measures.



This is as far as I can seem to get. I had solved this problem a couple of months ago and I still know the solution. However, I cannot seem to get show the angle measure now. Let this be a lesson to you all-------Right down everything you do!!!!!
