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): a² + b² = c².

If two angles are supplementary and one angle measures 100°, what is the measure of the other angle?

Back

The other angle measures 80° (180° - 100° = 80°).

Which equation would NOT be used to verify the Pythagorean Theorem for a triangle with sides 10, 11, and 18?

Back

11² + 18² = 10² is NOT used because it does not follow the theorem's principle.

Front

How do you determine if a triangle is a right triangle using the Pythagorean Theorem?

Back

You check if a² + b² = c² holds true, where c is the longest side.

What is the distance formula derived from the Pythagorean Theorem?

Back

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

If a camper travels 4 miles west and 3 miles north, how do you find the distance from the starting point?

Back

Use the Pythagorean Theorem: d = √(4² + 3²) = √(16 + 9) = √25 = 5 miles.
