Thursday 9/17/09

Hw; P113 #36 an 37 Note! The HW asks you to prove 2 theorems that are very similar to the proofs of theorem 2-1. Look for these proofs in your notes (Monday's, I think). They will make the HW a piece of (chocolate)cake!

Hi there!!!

Today we worked on more proofs. We studied a lengthy proof for theorem 2-8: Perpendicular lines intersect to form four right angles. If someone writes a proof with less than 12 steps, let me know!

Proof quiz tomorrow. YOU MAY USE the 2 handouts on Postulates & Theorems and the Definitions. There will be 2 proofs... and they will not require more than 6 steps. Yay ;)

Later skaters...

About Tania Lopez Hipple

I love math!!! By the way, I had a baby May 26, 2010 (William, little Will) and he is doing great! This is my 9th year teaching math and my 2nd year at TPA. I have been teaching geometry at least twice a day since 2004 so it is a math subject I know inside and out!

In 2000, I received my B.S. from UCLA for Applied Math and a minor in French. I love languages. I'm fluent in Spanish too. I was born in El Salvador and have lived in Los Angeles since 1981, when I was 5...are you doing some math yet? I was always good at math, so this definitely helped my interest in the subject. I actually applied to colleges as a math major because I couldn't think of another subject I could dedicate a few years to and not be bored! I had no idea I was going to be a teacher until 2001. I got a job teaching 8th grade algebra and was suddenly thrown into the world of the Los Angeles Unified School District. After 2 years, it hit me like a ton of bricks! I love teaching. I want to teach math forever! So the following year I earned my teaching credential and a masters in Multicultural Education from National University. It's now 2004 and I finally got to teach at the high school level. I worked at Birmingham High school until the day I literally got into my car and drove to Tempe- the Friday of the last day of the Fall semester this year, February 6, 2009.
