If you want to dilate an isosceles right triangle with a hypotenuse of 18 yd, to create a dilated image with a hypotenuse of 12 yards, what scale factor should you use?
A. 6 yd
B. 2/3
C. 3/2
D. 2/3 yard
To find the scale factor, we can divide the length of the desired hypotenuse (12 yards) by the length of the original hypotenuse (18 yards):
Scale factor = 12 yards / 18 yards
Simplifying this fraction gives us:
Scale factor = 2/3
Therefore, the correct answer is B. 2/3.
