Pythagorean Theorem --> Distance Between Two Points

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). It is expressed as: c² = a² + b².

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

Back

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

What is the distance between the points (3, 4) and (7, 1)?

Back

Using the distance formula: d = √((7 - 3)² + (1 - 4)²) = √(16 + 9) = √25 = 5 units.

If a right triangle has legs of length 6 and 8, what is the length of the hypotenuse?

Back

Using the Pythagorean Theorem: c² = 6² + 8² = 36 + 64 = 100, so c = √100 = 10.

What is the distance between the points (0, 0) and (3, 4)?

Back

Using the distance formula: d = √((3 - 0)² + (4 - 0)²) = √(9 + 16) = √25 = 5 units.

If the distance between two points is 10 units and one point is (2, 3), what could be the coordinates of the other point?

Back

Possible coordinates could be (2 + 10, 3) = (12, 3) or (2 - 10, 3) = (-8, 3) or (2, 3 + 10) = (2, 13) or (2, 3 - 10) = (2, -7).

What is the distance between the points (5, 5) and (5, 10)?

Back

Using the distance formula: d = √((5 - 5)² + (10 - 5)²) = √(0 + 25) = √25 = 5 units.
