Assessment items Lines R U, W T, and S V intersect at point Q. R U and S V are perpendicular. Lines W T passes through angle R Q V and angle S Q U.

Lines t and s intersect at point R. Obtuse vertical angles measure seventy-nine plus y degrees and four y minus eight degrees.

Line A K and line M J intersect at a right angle at point D. Line L C also passes through point D, forming angle A D C and angle J D C. Angle A D C measures four x degrees, and angle J D C measures three x minus eight degrees.
