Pythagorean theorem: find the length of the hypotenuse (Introduction)
Pythagorean theorem: find the length of the hypotenuse (Introduction)
What you'll learn
- Identify the hypotenuse in at least 4 out of 5 right triangles presented visually or described in text.
- Apply the Pythagorean Theorem (a² + b² = c²) to correctly solve for the length of the hypotenuse (c) in at least 3 out of 4 right triangle problems, given the lengths of the other two sides (a and b).
- Explain, in their own words, why the Pythagorean Theorem only applies to right triangles, using the terms 'legs' and 'hypotenuse' correctly.
- Solve for the length of the hypotenuse, expressing the answer with correct units (e.g., cm, m, in), for at least 2 out of 3 word problems involving right triangles.
