Distance (Pythagorean Theorem)

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 in a coordinate plane?

Back

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

What is the length of the diagonal of a rectangle with vertices at (x1, y1), (x2, y1), (x2, y2), and (x1, y2)?

Back

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

If a rectangle has a width of 6 units and a height of 8 units, what is the length of its diagonal?

Back

Using the Pythagorean Theorem, the diagonal d = √(6² + 8²) = √(36 + 64) = √100 = 10 units.

How do you find the distance between points (2, 4) and (2, -4)?

Back

Using the distance formula: d = √((2 - 2)² + (-4 - 4)²) = √(0 + 64) = √64 = 8 units.

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.

What is the relationship between the lengths of the sides of a right triangle and the Pythagorean Theorem?

Back

The lengths of the two shorter sides (legs) of a right triangle can be used to find the length of the hypotenuse using the Pythagorean Theorem: c² = a² + b².
