Pythagorean Theorem Intro

Pythagoras was.....

• A greek mathematician

• A russian gymnast

• An american astronaut

• A french chef

Which triangle could be you use the pythagorean theorem with?

• 
• 
• 
• 

A square means the angle is a​ (a)   angle that measures​ (b)   degrees.

• right
• 90
• acute
• obtuse
• 85
• 180

We use a square to denote a 90° angle because...

• All angles in a square measure 90°

• It's aesthetic.

• A circle wouldn't fit.

• Rectangles are sigma ohio.

Label the legs and hypotenuse

a

b

legs

hypotenuse

True or false: the hypotenuse is the shortest side on a triangle.

• True

• False

Fill in the pythagorean theorem. (You will have to have this memorized).

​ (a)   +​ (b)   =​ (c)  

The side lengths of the square are...

• 9, because 9 times 9 is 81

• 3 and 27, because 3 times 27 is 81

• 20.25, because 81 divided 4 is 20.25

• 40.5, because 2 times 40.5 is 81

True or false: the area of the green square and the area of the orange square would add up to the area of the blue square.

• True

• False

Which side is the hypotenuse?

• a

• b

• c
