If you want to dilate an isosceles right triangle with a hypotenuse of 18 yards, to create a dilated image with a hypotenuse of 12 yards, what scale factor should you use?

Answer 1

To find the scale factor, you need to divide the length of the new hypotenuse by the length of the original hypotenuse.

Scale factor = New hypotenuse length / Original hypotenuse length
Scale factor = 12 yards / 18 yards
Scale factor = 2/3

Therefore, you should use a scale factor of 2/3 to dilate the isosceles right triangle with a hypotenuse of 18 yards to create a dilated image with a hypotenuse of 12 yards.
