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 can be expressed as: c² = a² + b².

How do you calculate the slant height of a pyramid with a square base?

Back

The slant height (l) can be calculated using the formula: l = √(h² + (s/2)²), where 'h' is the height of the pyramid and 's' is the length of a side of the base.

What is the distance formula in a coordinate plane?

Back

The distance between two points (x₁, y₁) and (x₂, y₂) is given by: Distance = √((x₂ - x₁)² + (y₂ - y₁)²).

If Trent walks 40 yards north and 25 yards west, how do you find the distance from his starting point?

Back

Use the Pythagorean Theorem: Distance = √(40² + 25²) = √(1600 + 625) = √2225 ≈ 47.2 yards.
