Parmis is a content creator who has a passion for writing and creating new things. A parallelogram is a quadrilateral with opposite sides parallel. Dilation is a non-rigid transformation, which means that the distance between points in the preimage and image don't remain the same; the preimage and image are not congruent. where the coordinates of the vertices are, $A\left( x_{1}, y_{1} \right), B\left( x_{2}, y_{2} \right)\text{ }and\text{ }C\left( x_{3}, y_{3} \right),$, So, the coordinates of the vertices of a dilated triangle, would be $A\left( kx_{1}, ky_{1} \right), B\left( kx_{2}, ky_{2}\right)\text{ }and\text{ } C\left( kx_{3}, ky_{3} \right).$. If the scale factor is between 0 and 1, the image is a reduction (a shrink). The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Let A ( -2, 1), B (2, 4) and (4, 2) be the three vertices of a triangle. How can you find the scale factor of a dilation?
