parallel and perpendicular lines
TRANSCRIPT
Introduction:
• Many people use parallel and perpendicular lines and planes. You use them in your daily life; you will as well use it in your future. Who uses them? Do you know? Well there are a lot of them such as:
• Card architects.
• Piano makers.
• Rowers.
Vocabulary:
• Parallel lines: are coplanar that don’t intersect.
• Perpendicular lines: intersect at 90 degrees.
• Skew lines: are not coplanar and are not parallel and do not intersect.
• Transversal: Is a line that intersects 2 coplanar lines at two different points.
Vocabulary:
• Rise: difference in the y-values of two points on a line.
• Run: difference in the x-values of two points on a line.
• Slope: is the ratio of rise to run.
• Slope formula:
Parallel line?
The parallel line here is
Skew line?
Are skew lines in the figure shown.
Transversal line?
The red line is the transversal in each example
Identify the slope:
Slope?
Slope =
Example for Slope:
