When one leg=6 and the hypotenuse=10 then the other leg=?
What is 8?
200
When one leg=3 and the other leg=5 then the hypotenuse=?
What is the square root of 34
200

200

How can you test if three side lengths form a RIGHT triangle?

Plug in the values into the pythagorean theorem and see if both sides equal eachother.

300

What is the formula for the Pythagorean Theorem?

What is a^2+b^2=c^2

300
When one leg=5 and the hypotenuse=13 then the other leg=?
What is 12?
300
When one leg=6 and the other leg=7 then the hypotenuse=?
What is the square root of 85?
300

What do we call multiplying a number by itself?

squaring a number

300

Do the side lengths form a triangle? 1, 2, 3

No because 3 isn't larger than 3

What is 24?
400
When one leg=10 and the other leg=9 then the hypotenuse=?
What is the square root of 181?
400
The side that always has the longest length in a right triangle
What is the hypotenuse?
400

Do these 3 side lengths form a triangle? 5, 8, 12

Yes because 5+8 = 13 which is larger than 12

500

What is the only type of triangle that works with the Pythagorean Theorem. (Or a triangle with an angle measuring 90 degrees)

Right Triangle

500

When one leg=21 and the hypotenuse=35 then the other leg=?

What is 28?

500
When one leg=15 and the other leg=22 then the hypotenuse=?

500
The operation we used to "get rid" of something squared.
What is taking the square root?
500

Do these three side lengths form a RIGHT triangle? 4, 5, 2

22 + 42= 52  simplifies to 20=25 so, no it's not a right triangle!
