Hello everyone! Just wanted to let you know that last week I accidentally left a blank spot in my writing. I meant to say that "using the angles of incidence and reflection, we must create..." but I forgot to fill it in. Sorry!

So, this week I'm posting specifically about my favorite postulate. I would have to say that my favorite postulate is the Corresponding Angles Postulate, which states that when two parallel lines are cut by a transversal, the resulting corresponding angles are congruent. Remember, a transversal is a line that cuts across two or more other lines, and corresponding angles are in the same position in relation to the transversal. I find this postulate very helpful when proving things, but I constantly have to remind myself that it's only for parallel lines!

Hope your week goes well! There's only thirteen days until Christmas...I'm so excited! :)
