I need help with this question.

AngleQRP and AngleTUR

Step-by-step explanation:

When 2 lines are cut by another line (the transversal is the line cutting those lines), the angles in matching angles are congruent.

We need to find corresponding angles, which are 2 angles which are on the same side, but one is on the inside and one is on the outside of the transversal. AngleQRP and AngleTUR match this definition, so that is our answer. the  image might help you understand corresponding angles.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
