1.2 Pythagorean Theorem 8.6C, 8.7C D

Front

What is the Pythagorean Theorem?

Back

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.

Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side in a right triangle, opposite the right angle.

Front

Calculate the hypotenuse: a = 3, b = 4. What is c?

Back

c = 5 (using the Pythagorean Theorem: 3² + 4² = 9 + 16 = 25, √25 = 5).

If a = 5 and c = 13, what is b?

Back

b = 12 (using the Pythagorean Theorem: 5² + b² = 13², 25 + b² = 169, b² = 144, b = 12).
