1
Bell work: Once bell work is completed, turn in, along with test corrections, and any homework you have.
2
Proof of the Congruent Complements Theorem
3
Proof that Right Angles are Congruent
4
Proof that congruent supplements are right angles
5
3.1: Lines and Angles
6
What is necessary for lines to intersect?
Are there any pairs of lines which don’t intersect?
7
Parallel lines are coplanar lines that do not intersect
Parallel lines are coplanar lines that do not intersect. Parallel lines have the same slope Skew Lines are non-coplanar. They are not parallel and do not intersect Parallel Planes are planes that do not intersect. Segments and Rays can also be parallel or skew
8
Identify the line relationships
10
When a line intersects two or more other lines…
A Transversal is a line that intersects two or more COPLANAR lines at distinct points. Angles 3, 4, 5, and 6 are interior angles Angles 1, 2, 7, and 8 are exterior angles
12
3.2: Properties of Parallel Lines
13
Postulate 3-1 If a transversal intersects two parallel lines, then same-side interior angles are supplementary
15
Proof of Theorem 3.1
17
Using the same diagram and given statement, prove that angles 1 and 7 are congruent
