If I Were A Teacher For A Day

Me being a teacher for a day

By Gary Harley

Lesson plan Today I will teach my class about the Pythagorean therom. I will start off telling them about it. Then I will teach them how to set up the equation for the problem. Then I will give them some examples to practice the Pythagorean therom.

A little history for the students The Pythagorean therom came from a Greek mathematician named Pythagoras. He love math and than one day he got to thinking, how do you determine the length of the third side of a right triangle. And so then he set out how to find out how to find the formula and that is what is know as the Pythagorean therom.

Step-By-Step Procedures A triangle has 3 sides a, b, and c. a measures 3 inches long, and b measures 4 inches long. what is the length of the third side c? We use the formula: A²+B²=C² So it would look like this:3²+4²=C² And then we would simplify: 9+16=C² Which would then equal:25=C² And then you would find the square route of 25 which we all know equals 5 and that is the answer. Write it out like this C=5.

Step-By-Step procedures(continued) A telephone pole casts a shadow that is 20 feet long and the pole is 15 feet tall what is the distance from the end of the shadow to the top of the pole?

We use the formula:A²+B²=C² So it would look like this:20²+15²=C² And then we would simplify:400+225=C² Which would then equal:625=C² And then you would find the square route of 625 probably with a calculator and it would equal 25. Write it like this:C=25.

Definitions Legs: Two sides of a right triangle that form a right triangle. Hypotenuse: the side opposite the right angel in a right triangle. Pythagorean therom: if a right triangle has legs of lengths a and b and a hypotenuse of length c, then A²+B²=C².

Homework

To show that my students have learned the lesson, I will give them homework to do so they can practice it.
