A designer creates a drawing of a triangular sign on centimeter grid paper for a new business. The drawing has sides measuring 9 cm, 12 cm, and 15 cm, and angles measuring 37°, 53°, and 90°. To create the actual sign shown, the drawing must be dilated using a scale factor of 30. Part 1 out of 4
Find the lengths of the sides of the actual sign.

Which lines are parallel? justify your answer. lines p and q are parallel because same side interior angles are congruent. lines p and q are parallel because alternate exterior angles are congruent lines l and m are parallel because same side interior angles are supplementary lines l and m are parallel because alternate interior angles are supplementary.
