In a right triangle, the hypotenuse connects the two legs at the right angle. Using the Pythagorean theorem:", "\[\nc = \sqrt{a^2 + b^2}\n\]", "Here, \( a = 9\ \ ext{cm} \), \( b = 12\ \ ext{cm} \). Calculating step by step:", "\[\na^2 = 81,\ b^2 = 144 \quad \Rightarrow\quad c = \sqrt{81 + 144} = \sqrt{225} = 15\ \ ext{cm}\n\]", "So, the hypotenuse measures exactly 15 cm. For the area, use:", "\[\n\ ext{Area} = \frac{1}{2} \ imes \ ext{leg}_1 \ imes \ ext{leg}_2 = \frac{1}{2} \ imes 9 \ imes 12 = 54\ \ ext{cm}^2\n\]", "This straightforward process makes it easy to apply in worksheets, construction apps, and digital design tools—platforms millions of Americans access daily. Understanding this relationship between leg lengths, hypotenuse, and area supports both academic growth and real-life problem solving.", "### Common questions people ask about A right triangle has"]
