Question

Triangle STU is dilated by a scale factor of 5 centered at the origin. Draw the new image S'T'U'.

Answer 1

Given the triangle STU.

From the plot, the coordinates are evaluated to be

$\begin{gathered} S(-2,2) \\ T(2,2) \\ U(2,0) \end{gathered}$

When the triangle is dilated by a scale factor of 5, the coordinates of the new image S'T'U' becomes

$\begin{gathered} S^{\prime}(-10,10) \\ T^{\prime}(10,10) \\ U^{\prime}(-10,0) \end{gathered}$

The graph of the new image is given below
