you are quilting blocks out of squares…?
you are quilting blocks out of squares. if a block has a diagonal of 8 cm, how long is each side to the nearest tenth of a cm? choices are [a] 5.7 cm [b] 11.3 cm [c] 12.3 cm [d] 4.7 cm
You can either use the properties of 45-45-90 triangles or the Pythagorean theorem for this problem. If you use 45-45-90 triangle properties, the hypotenuse is 8. The legs of a 45-45-90 triangle have length a and the hypotenuse has length a*square root of 2. Since you are given the hypotenuse of 8, the leg must have length 4*square root of 2.
Using the Pythagorean Theorem, x^2 + x^2 = 8^2
2x^2 = 64
x^2 = 32
x = square root of 32 = 4*square root of 2.
The answer should be a.
