~ angels part 1 ~

~ When I have to set an equation that equal 90 or 180. I know because of the angels. For example, if its just a line I know that its going to equal 180 and if it looks like an L with a little box its going to equal up to 90. When we set an angles equal to each other that means that they are vertical. When you are solving for just x you are not solving the problem correctly because you are just finding the value of x. So now you have to plug it in to find the degree of that area, of the angle. The word congruent means that they are the same. Yes vertical angles are congruent because they have the same shape and measure the same. Not all the time complementary are congruent sometimes they can measure differently and there shapes meant be bigger or smaller than one another. The same is for supplementary angles they can measure the same or they don't.... Another angle that are congruent are vertical....../
