An isosceles triangle must have two equal angles.
Also, ANY triangle must have 3 angles that add up to 180 degrees.
If one angle is 80 degrees, there are 2 options:
A) One 80 degree angle, and 2 angles of 50 degrees each
B) Two 80 degree angles, with the 3rd angle being 20 degrees
Only one possibility with one 80 degree angle......

Which part?? Starting at the top, please identify which statement you do not understand. To start: Do you understand that an isosceles triangle must have 2 equal sides? Do you understand that the 3 angles of a triangle must add up to 180 degrees? If so, we can go from there....
