Yes, the Pythagorean theorem gives the exact measurements always. It can be backed up by proofs and sin, cosine, etc.

the measurement is not always exact and say you were to measure a football field and your measurement were to be exact it would be close to impossible
Yes, he must have proved his own Theorem otherwise it would not have been adopted by mathematicians across the globe. I'm sure you could test out the theorem: check whether c2 really does equal b2 + a2 in a manual measurement of a triangle; though this is less accurate and not as precise as the Theorem.
false
Since the rectangle has right angles, you can use Pythagoras' Theorem in this case.
Using Pythagoras' theorem the length of the hypotenuse is 39 units of measurement.
If you know the length of 2 sides of a triangle, you can always find the length of the third using Pythag. Pretty neat!
The formula for the Pythagorean Theorem is a2+b2=c2 :] The Pythagorean Theorem is finding the measurements in a right triangle. The side of the triangle across from the right angle is called the hypotenuse and the two other sides are called the legs :3 I hope I could help! <3
41.3 is an exact measurement.
Using Pythagoras' theorem: 425
the unknown measurement of a side of a triangle
By Pythagoras's theorem it is 15*sqrt(2) = 21.213 approx.
The exact measurement in inches of an M3 screw size is 0.118 inches.
The exact measurement in millimeters of an M4 screw size is 4 millimeters.
What do you mean by "exact measurement"? Do you wish to determine the cylinder's height? Its diameter? Its surface area? Its volume?
The exact measurement of an M4 screw size in inches is approximately 0.1575 inches.
Is as exact as possible
