How do you use the pythagorean theorem?

Answer 1

Abigail Allen

Pythagorean theorem: #a^2+b^2=c^2#

This only applies to right angle triangles (one of the angles is #90^@#s)

If you want to find the length of a triangle where it's A=3 B=4 C=?

you do #3^2+4^2=?#

#9+16= 25#

and

#5^2=25#

Therefore

C=5

you can also use it to find A or B by doing #C^2-A^2=B^2# or #C^2-B^2=A^2#

The Pythagorean theorem is used to find the length of one side of a right triangle when the lengths of the other two sides are known. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. The formula is written as a^2 + b^2 = c^2, where a and b are the lengths of the two legs of the triangle, and c is the length of the hypotenuse. To use the theorem, you would substitute the known values for a and b into the formula and solve for c.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
