what makes Pythagoras theorm true? is it because variance of a straight line is zero?
Pythagoras Theorem is a mathematical concept that 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 other two sides.
Pythagoras Theorem is used to find the length of a missing side in a right triangle, given the lengths of the other two sides. It is also used in various fields such as engineering, architecture, and physics to calculate distances, areas, and volumes.
Variance of a straight line is a measure of how spread out the data points are from the line of best fit. It is calculated by finding the average squared distance between the data points and the line.
In the context of a straight line, Pythagoras Theorem is used to calculate the sum of squared distances between the data points and the line of best fit. This sum of squares is then divided by the number of data points to find the variance of the straight line.
No, the variance of a straight line is not always zero. It depends on how closely the data points align with the line of best fit. If the data points fall perfectly on the line, the variance will be zero. However, if there is some variation, the variance will be greater than zero.
