What are dilations?

Draw each letter enlarged by a scale factor of $1.5, 2, 2.5, 3,$ and $4$ (choose a different scale factor for each one).

Draw each letter enlarged by a scale factor of $1.5, 2, 2.5, 3,$ and $4$ (choose a different scale factor for each one) and compare the lengths of the each edges of each figure with the corresponding edges in the enlarged figure.

Draw each letter enlarged by a scale factor of $1.5, 2, 2.5, 3,$ and $4$ (choose a different scale factor for each one) and compare the angles in each figure with the corresponding angles in the enlarged figure.

A rectangle has side lengths $2 \mathrm{cm}$ and $8 \mathrm{cm}$. It is enlarged with scale factor $1.25$. Draw the original rectangle and the enlarged rectangle.
