Respuesta :
The length of xy in the triangle XYZ is 9 units if xyz is dilated to create triangle x prime, y prime and z prime.
Given triangle xyz is dilated to create x prime, y prime and z prime.The length of oz is 2, the length of Zz Prime is 4,the length of x prime y prime is 9 and the length of side y prime z prime is 12.
Dilation is basically technique of creating similar shapes. Each point is streched outwards from the center point by multiplying the scale.
After dilation the side of the shape used to reduce according to factor. It is reduced by number of times of factor.
The line xy is equal to 9 units after dilation by a factor of 3. So the length of xy is 9/3.
=3 units.
Hence the length of side xy is 3 units if xyz is dilated to create x prime, y prime and z prime.
