We started off class by looking over our Chapter 2 diagnostic work sheet and correcting a classmates to show Mr.Banow our knowledge in this unit so far.
Converse is a statement that is formed by switching the premise and the conclusion of another statement.
Next we worked on page 72 which is reviewing parallel lines and transversals.
We reviewed what Alternate Interior and Exterior angles were.
Alternate interior angles are two non-adjacent interior angles on opposite sides of a transversal. Which is angles 3,6 and 4,5.
Alternate exterior angles are two exterior angles formed between two lines and a transversal, on opposite sides of the transversal. Which is angles 1,8 and 2,7.
We also reviewed what Supplementary and Complementary angles were. Two angles are Supplementary angles if they add up to 180 degrees. These two angles (140 degrees and 40 degrees) are Supplementary Angles, because they add up to 180 degrees. These two angles (40 degrees and 50 degrees) are Complementary Angles, because they add up to 90 degrees.
The next person to blog will be, AARON. :)
OH YAH, and don't forget to bring a compass, protractor and ruler ASAP.
