Question
The hypotenuse of an isosceles right triangle is 10. What are its other two side lengths? [Hint: Find the area of the square composed of two such right triangles.]
Answer

If a is the length of two equal sides of an isosceles right triangle, then a 2 + a 2 = 102 ⇒ 2a 2 = 100 ⇒ a 2 = 50 ⇒ a = √50 ⇒ a = 5√2 2.4 Combining Two Different Squares Figure It Out (Page 47)
