By definition, two shapes are congruent if you can map one onto the other using rigid transformations (a sequence of one or more
rotations, translations, and reflections). Since any sequence of rigid transformations performed on a triangle results in a congruent triangle, what does that imply about the corresponding side lengths and angle measures for two congruent triangles?
Set up a proportion. If 12 3/5 feet can be traveled in one minute, then make that a fraction. 12 3/5 over one equals X over 30. Cross multiply 12 3/5×30 equals 1 X and solve.
