Slope, Equivalent Fractions/Ratios, and Parallel Lines
Let’s work on slope again. We’ll use snap cube’s to create rise/run fraction “Ls”. Then we’ll use them to draw slope lines on paper. Then we’ll try adding to the Ls:
- What happens if we double the rise, but not the run?
- What happens if we double the run, but not the rise?
- What happens if we double both?
Watch this on Parrallel lines: https://www.youtube.com/watch?v=oJaMUVv4VXE
Parallel lines always have the same slope, but this can be shown by any equivalent fraction/ratio. This is what allows designers to use different measurements and yet maintain the same slope of a trail (or a roof).
- Pick 4 fractions. Create slope Ls. Draw the lines. How do they compare? If none were parallel, create a fraction that makes at least one parallel line.
