What do you do to get the square root answer on a calculator?
You press the square root button, type in the number, then press equals
How can you confirm whether a triangle is a right-angled triangle?
If the sum of the squares of the two shorter sides equal the square of the hypotenuse, the triangle is a right angled triangle.

a and b are referred as...
What is the equation for the Pythagorean Theorem?
a2+b2=c2
Would this be a right-angled triangle?
32+22=52?
9+4=25? 13 is not equal to 25
What can I find examples of Pythagoras' Theorem?
My notebook
when the numbers are on both short sides, you *add* or *subtract*?
Add
Explain what the Pythagorean Theorem is?
If I square the two shorter sides then add them together, the result will be the same as the hypotenuse squared. It is a right triangle.
102+242=c2
100+576=c2 square root of 676 = c 26=c

Square rooting
Explain the step by step process of the theorem if the numbers are on one of the short sides and the hypotenuse?
Square the numbers, subtract the short side number from the hypotenuse, square root the difference. The answer is ___ = a/b
172+b2=192
289+b2=361 361-289=b2 square root of 72=b 8.5=b
