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 in a coordinate plane?

Back

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

If the coordinates of two points are (3, 4) and (7, 1), what is the distance between them?

Back

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

What is the significance of the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle, and is crucial in applying the Pythagorean Theorem.

What is the relationship between the sides of a right triangle?

Back

In a right triangle, the sum of the squares of the two shorter sides (legs) equals the square of the longest side (hypotenuse).

What is the formula for finding the length of a side in a right triangle if the lengths of the other two sides are known?

Back

If the lengths of the two legs (a and b) are known, the length of the hypotenuse (c) can be found using c = √(a² + b²).

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.
