📚 Topic Summary
The Pythagorean Theorem is a fundamental concept in geometry that describes the relationship between the sides of a right triangle. It states that the sum of the squares of the two shorter sides (legs or cathetus) of a right triangle is equal to the square of the longest side (hypotenuse). Visually, this can be represented by constructing squares on each side of the triangle; the area of the square on the hypotenuse is equal to the combined areas of the squares on the other two sides.
This activity will guide you to visually understand and verify the theorem by constructing and measuring these squares, making the abstract concept more concrete and intuitive. Get ready to cut, measure, and discover the magic of the Pythagorean Theorem!
🧮 Part A: Vocabulary
- 📐 Term: Hypotenuse Definition: The side opposite the right angle in a right triangle.
- 📏 Term: Leg (or Cathetus) Definition: One of the two shorter sides of a right triangle that form the right angle.
- ⬛ Term: Square Definition: A quadrilateral with four equal sides and four right angles.
- ➕ Term: Sum Definition: The result of adding two or more numbers.

✍️ Part B: Fill in the Blanks
The Pythagorean Theorem states that in a right triangle, $a^2 + b^2 = c^2$, where $a$ and $b$ are the lengths of the ______ and $c$ is the length of the ______. This means that the ______ of the squares of the legs is equal to the ______ of the square of the hypotenuse. Visually, we can see this by drawing ______ on each side of the triangle and comparing their areas.
