Vertical Angles ay yung mga angles na nag form ng X. For example, E and H, F and G and sa kabila, I and L, J and K. Congruent sila or has same angle. So, sa E and H, if si E is 30° meaning si H is 30° din.
Supplementary Angles ay yung mga magkatabi na hindi pa X. For example, E and G, E and F, F and H, tas G and H. And sa kabila, I and J, J and L, L and K, K and I. The sum of these angles are 180°. So, kunwari yung I and J. If si I is 50° meaning si J is 130°.
