Pythagorean Theorem and Distance Formula

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.

What is the Distance Formula?

Back

The Distance Formula is used to determine the distance between two points (x1, y1) and (x2, y2) in a coordinate plane. Formula: d = √((x2 - x1)² + (y2 - y1)²).

If a right triangle has legs of lengths 3 and 4, what is the length of the hypotenuse?

Back

Using the Pythagorean Theorem: c² = 3² + 4²; c² = 9 + 16; c² = 25; c = 5.

What is the length of the missing side if one side is 6 and the hypotenuse is 10?

Back

Using the Pythagorean Theorem: 10² = 6² + b²; 100 = 36 + b²; b² = 64; b = 8.

Calculate the distance between the points (2, 3) and (5, 7).

Back

Using the Distance Formula: d = √((5 - 2)² + (7 - 3)²) = √(3² + 4²) = √(9 + 16) = √25 = 5.

What is the distance between the points (1, 1) and (4, 5)?

Back

Using the Distance Formula: d = √((4 - 1)² + (5 - 1)²) = √(3² + 4²) = √(9 + 16) = √25 = 5.

If Becky walks 6 blocks North and 8 blocks West, how far is she from the starting point?

Back

Using the Pythagorean Theorem: d = √(6² + 8²) = √(36 + 64) = √100 = 10 blocks.
