Journal Entry 9: Angles Part 1

I know when to set an equation equal to 90 or 180 when you determine if the angle is a right angle or a straight line and/or congruent. When we set angles equal to each other it means that we are putting angles together that are congruent. When we are only solving for x, it is not correctly solve because, if we solve for x it doesn't mean that we solve for the measurement of the angle, so we must plug in what x equals to solve the problem correctly. The word congruent means the same. Vertical angles are congruent because vertical angles have the same measurement. Complementary angles and supplementary angles are not congruent. Other types of angles that are congruent are corresponding angles.

    Hi Rotceh;

    From reading your blog I learned that Complementary angles and Supplementary are not congruent.Also what part I did not quite understand is why x is not correctly solve.I also learned that when you set an equation equal to 90 or 180 you will find out wheather it is a right angle or a straight line and/or congruent.

    Hey Stephanie,

    Thanks for being honest, I meant that when you are solving for x, it doesn't mean you've found the answer unless you plug it in. Thanks a Lot. I hope you liked my blog.
