Answer:
When three squares are joined at their vertices to form a right triangle, the combined area of the two smaller squares is the same as the area of the largest square.
Explanation:
f the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. for Example: ΔABC, if c2=a2+b2 then ∠C is a right triangle, ΔPQR being the right angle. hope this helps
