IM Geo.3.16 Lesson: Bank Shot
What do you notice? What do you wonder?
You need to make a bank shot. Sketch the path of the cue ball so it will bounce off of the bottom side and knock the solid orange 5 ball into the upper right corner pocket.
A true bank shot will create two similar right triangles. Determine the measures of the triangles you drew. Are they similar?
Calculate the exact point on the bottom side to aim for and then precisely draw the path of the ball.
How would you hit the ball so that it will end in the hole after one stroke?
Use mirrors to measure the height of a tall object. Label this image with the measurements you made.
Calculate the unknown height.
What if you don’t have a mirror when you’re trying to measure the height of something too tall to measure directly?
Brainstorm as many methods other than the mirror method as you can.
Add to your brainstorm by:
Pick a method you would like to try, and use it to measure the height of the object your teacher assigns you.
