Below are sample questions representative of the exercises included on this worksheet and related 8.128 Explaining the Pythagorean Theorem Conceptually skill assessments:

Problem 1Difficulty: Hard
Which statement best summarizes the Pythagorean Theorem conceptually?
AIn any triangle, the longest side equals the sum of the shorter sides.
BIn any right triangle, all three side-squares have equal area.
CIn any triangle, the area of the triangle itself equals the square on the longest side.
DIn any right triangle, the square built on the hypotenuse has the same area as the two squares built on the legs combined.
Solution & Explanation:This wording captures the core conceptual meaning of a2 + b2 = c2.
Problem 2Difficulty: Hard
If a triangle's side lengths satisfy a2 + b2 = c2 with c as the longest side, then the largest angle of the triangle is a right angle.
ATrue
BFalse
Solution & Explanation:This is exactly the converse of the Pythagorean Theorem.
Problem 3Difficulty: Hard
A teacher asks why the Pythagorean Theorem is geometric and not just algebraic. Which answer is best?
ABecause algebra and geometry can never overlap.
BThe symbols come from areas of squares built on the sides of a triangle, so the algebra represents a geometric idea.
CBecause geometric ideas never use equations.
DBecause the theorem is really about perimeter hidden inside exponents.
Solution & Explanation:The equation is meaningful because each squared term has a geometric interpretation as square area.
