Right Triangles & Pythagorean Theorem
In a right triangle, the areas of squares on the legs combine to equal the area of the square on the hypotenuse, yielding a^2 + b^2 = c^2.
What you'll learn
- Identify the hypotenuse as the side opposite the right angle in any orientation.
- Explain a² + b² = c² as an area relationship.
- Use the theorem only when a right angle is established.
- Take a square root after solving for a squared side length.
- Create right triangles from displacement, altitude, or coordinate change.
