Pythagorean Theorem, Distance, and Midpoint

Front

What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Formula: a² + b² = c².

How do you calculate the distance between two points (x1, y1) and (x2, y2)?

Back

The distance d can be calculated using the formula: d = √((x2 - x1)² + (y2 - y1)²).

What is the formula for finding the midpoint of a segment with endpoints (x1, y1) and (x2, y2)?

Back

The midpoint M can be found using the formula: M = ((x1 + x2)/2, (y1 + y2)/2).

How do you find the endpoint of a segment if you know one endpoint and the midpoint?

Back

If A(x1, y1) is one endpoint and M(xm, ym) is the midpoint, the other endpoint B(x2, y2) can be found using: x2 = 2*xm - x1 and y2 = 2*ym - y1.
