The frame of a bridge is constructed of triangles, as shown below. a large triangle is made up of 4 smaller triangles within the larger triangle. vertical line t u cuts the large triangle in half. lines u s and u v are diagonal from point u and go up to each side. angle s u t is 45 degrees and angle t v u is 98 degrees. line segment t v is 20 feet and line segment s u is 14 feet. what additional information could you use to show that δstu ≅ δvtu using sas? check all that apply.
