Exploring Parallel Lines

In our last class we started chapter 2. We learned about identifying relationships among the measures of angles formed by intersecting line. We learned about transversall lines which is a line that intersects two or more other lines at distinct points. We learned about exterior angles which is the angle that is formed by a side of a polygon and the extension of an adjacent side.  We learned about interior angles which are any angles formed by a transversal and two parallel lines that lie inside the parallel lines. We learned about corresponding angles which is one interior angle and one exterior angle that are a non-adjacent and on the same side of the transveral. Converse is a statement that is formed by switching the premise and the conclusion of another statement. A key summary to follow is when a transversal intersects a pair of parallel lines, the corresponding angles that are formed by each parallel line and the transversal are equal. things you need to know is when a transversal intersects a pair of non-parallel lines, the corresponding angles are not equal. There are also other relationships among the measure of the eight angles formed when a transversal intersects two parallel lines. To do all of this you will need some materials such as a dynamic gemoetric software or a ruler and protractor.

Our class did a hand out assignment on this and then we went over all the answers as a class and i believe it went very well because our class is very smart.

Next will be michelle :)
