Triangle rst was dilated by a scale factor of one-half. the image, triangle r's't', is an isosceles triangle, with each leg measuring 8 units.
point q is the center of dilation. isosceles triangle r s t was dilated to smaller triangle r prime s prime t prime. sides r s and r t are 8 units long.
what is the length of a leg of the pre-image, triangle rst?
4 units
8 units
16 units
20 units

The length side of the pre-image is 16 units

Step-by-step explanation:

we know that

The length side of the image is equal to the length side of the pre-image multiplied by the scale factor

or

The length side of the pre-image is equal to the length side of the image divided by the scale factor

in this problem we have that

The scale factor is 1/2

The length side of the image is 8 units

therefore

8/(1/2)=16 units

The length side of the pre-image is 16 units

i would love   to but there is no graph shown
