3. Reviewing the Basics
• The Pythagorean theory states that the triangle must have a right angle in
order to use it.
• This is used when you are given the height, the base, and are looking for the
length of the hypotenuse.
• a^2+b^2=c^2
5. Why Pythagorean Theorem?
• You can use this in the real world.
• When buying a television.
• When painting a wall and placing the ladder.
• Used for distance.
6. Class Goal
• Show students math is used outside the class.
• Get the students to understand real world problems.
• Have students come up with their own.
8. Real World Problem 2
You are standing 10 feet
away from a 30 foot
tree. What is the length
of the distance between
you and the top of the
tree?
9. Real World Problem 3
• You're playing a dogleg left in golf (a hole that bends about 90 degrees to the
left). You could play it safe and hit it short onto the fairway. Or, you could try
to hit it over the trees onto the green. The problem is, you don't know how
far it is.
10. Homework
• Come up with your own real world problem.
• Swap problems with a partner in the next class.
