Geometry (math)

Question

RSTU is a parallelogram. If m∠TSV = 31° and m∠SVT = 126°, explain how you can find the measure of ∠URV. Show all steps of your work, and refer to any properties of triangles, parallelograms, or triangle congruency theorems as necessary to justify your response.

Answer 1

∠STV and ∠RUV are alternate interior angles of two parallel lines cut by a transversal.
