This video focuses on how to convert angles
to distances by using trigonometric functions. The presenter begins in a park
measuring the sides and angles of the cardboard skyscrapers that were built by
a group of people. With discussions about corresponding sides and angles, a
conclusion is drawn that larger angles have larger corresponding sides. The
presenter explains the Pythagorean Theorem – that the sum of the legs squared
is equal to the hypotenuse squared. One example used to explain this concept is
the height of a window on a house.

Class discussion questions
1. What kind of triangle does the
Pythagorean Theorem apply to?

triangles such as 30-60-90 and 45-45-90 triangles. Use the trigonometric
functions to show that the side lengths are correct.
3. What are some other instances in which a
person may need to use Trigonometric functions? Include anything that you may
use in your life and you can also include that they can be used to find
distances between celestial bodies or the distance from shore to a point at sea
4. The mnemonic of SOHCAHTOA is expanded to
“Stephen, Oh Heck, Crocodiles And Hedgehogs Took Our Apples.” What other words
