Warmup for Pythagorean Project

WARMUP FOR PYTHAGOREAN PROJECT On your graph paper, do the following:

Draw a triangle with the following sides: Leg 1 = 3 units (squares) Leg 2 = 4 units (squares)

Draw the squares that the sides form. Find the area of each square.

What is the relationship between the areas?Try to write an equation for the relationship

NOW LETS FIND THE SIDE LENGTH OF THE HYPOTENUSE

The relationship we just found is Now let’s find the hypotenuse:

Please substitute what you know into the equation and follow PEMDAS to find .

How do we get rid of the exponent of 2?

Let’s make a flow map of this procedure.

USING THE PYTHAGOREAN THEOREM Project:

You will be given a situation and you are to solve it with the Pythagorean Theorem. You will create a poster with the following on it:

The situation in words A picture of the situation with correct labels and

units The math that explains how to get the answer. Your answer in a complete sentence (remember

mmm… sentences from Math Modeling) Round your answer to the nearest tenths place
