When you set an equation equal to 90 or 180 you have to determine whether the angle is 180 or 90 by looking at the angle and seeing if it is 180 or 90 or if it is congruent or not. We we set angles equal to each other in a equation that means that the angles are vertical and or congruent. If we solve for x that doesn't mean that we finished solving for the equation. The answer will not be correct because we have to solve for the missing side not for x. Do you know what congruent means? Congruent means the same. Vertical angles are congruent they are across from each other and they measure the same. Complementary and supplementary angles are not congruent. Angles that are congruent are corresponding angles and vertical angles.

Hi Mayelin,
Your blog was nice and i enjoyed reading it. One thing i learned from it is, that vertical angles are congruent because they are across from each other and there the same angles.
