1 Angle Types and Parallel/Perpendicular Lines

2 Naming an angle:... A B C The “corner” or angle that you are naming should be the middle letter when naming the angle.... A B C

3 Classifying an angle by size: 180° = ___________ angle straight 90°< v <180° = ___________ angle v (Angle is bigger than 90, but smaller than 180) obtuse 90° = ___________ angle right < 90° = ___________ angle (Angle is smaller than 90) acute

4 Parallel Lines Parallel Lines are lines that have the ________ slope. same Find the slope of the line containing the following points: A (2, 4) B (3, 8) Write an equation for a line parallel to the above line.

5 Perpendicular Lines Perpendicular Lines are lines that have ________________ slopes. negative reciprocal Find the slope of the line containing the following points: A (2, 4) B (3, 8) Write an equation for a line perpendicular to the above line.
