GEOMETRY 1.5 Did You Find a Parking Space?

1.5 Parallel and Perpendicular Lines On The Coordinate Plane Objectives Determine whether lines are parallel. Identify and write the equations of lines parallel to given lines. Determine whether lines are perpendicular. Identify and write the equations of lines perpendicular to given lines. Identify and write the equations of horizontal and vertical lines. Calculate the distance between a line and a point not on a line. Page 61: Need a reader for the launch

Field Trip Leave all of your stuff here I will lock the door We are going to the parking lot Other classes are in session Go to the main stairs, go down to the main floor, turn left and walk toward the athletic wing. Turn left and exit by the pool. We will meet on the sidewalk next to the bus parking area.

Wrap-Up / Formative Assessment Describe the slopes of parallel lines Describe the slopes of perpendicular lines Pg. 74 Talk the Talk: Due on Wednesday

Refresh: 1.5 Parallel and Perpendicular Lines On The Coordinate Plane Talk the Talk Keep until tomorrow after we discuss perpendicular Parking Lot Visit Parallel Lines Slopes of Parallel Lines Objectives Determine whether lines are parallel. Identify and write the equations of lines parallel to given lines. Determine whether lines are perpendicular. Identify and write the equations of lines perpendicular to given lines. Identify and write the equations of horizontal and vertical lines. Calculate the distance between a line and a point not on a line.

Problem 2: More Parking Spaces Need a protractor For #3, the relationship is between two lines at once either parallel or perpendicular. Collaborate 1-6 (10 Minutes)

Problem 3: More Parking Spaces 3a) All lines are parallel The slopes are equal 3b) The lines are perpendicular The slopes are different 3c) The lines are perpendicular The slopes are different 3d) The lines are perpendicular The slopes are different

Problem 2: More Parking Spaces

Not Opposite Reciprocals Then Not Perpendicular

Problem 3: Horizontal and Vertical Collaborate 1-5 (5 Minutes)

Problem 3: Horizontal and Vertical Collaborate 6-10 (4 Minutes) Formative Assessment (6-10) We will discuss as a class tomorrow along with the Talk the Talk

Problem 3: Horizontal and Vertical Collaborate 6-10 (4 Minutes) Formative Assessment (6-10) We will discuss as a class tomorrow along with the Talk the Talk 8) Through (2, -1) Horizontal Lines are always y = # Slope = 0 y = -1 Vertical Lines are always x = # No Slope / Undefined Slope x = 2

Problem 3: Horizontal and Vertical 9) Perpendicular to x = 5 through (1, 0) Perpendicular to a vertical line is a horizontal line y = 0 10) Perpendicular to y = -2 through (5, 6) Perpendicular to a horizontal line is a vertical line x = 5

Problem 4: Distance Between Lines and Points Together 1 The shortest distance between a line and a point not on the line is the length of the perpendicular segment drawn from the point to the line.
