Supplementary angles are either of 2 angles that measure to 180 degrees. Adjacent angles have a common vertex and share the same side. Vertical angles are opposite sides that are made by a intersecting line(s). Complementary angles are either of 2 angles that measure 90 degrees. So now knowing what each of them mean you can now use the elimination method to solve this, where this is a multiple choice question with one or more answers it'll be a little easier to solve. So, you can eliminate vertical cause there on the same side. So you are left with A, B, D. Triangles are 180 degrees in total so where that triangle type figure is divided/ split in half it would be 90 + 90 = 180 degrees. So we now know both A, D are true. We now have to figure out for B) Adjacent angles. The two triangles are on the same side and are right beside each other so the correct choices are: A B D Good luck!!!
