Properties of Parallelograms
Angles of a polygon that share a side are consecutive angles. A parallelogram has opposite sides parallel. Its consecutive angles are same-side interior angles so they are supplementary. In ABCD, consecutive angles B and C are supplementary, as are consecutive angles C and D.
Find mS in RSTW .
R and S are consecutive angles of a parallelogram.
Solve for x
2x-10=65-x. First you Add to 2x since it's a
X-10=65. Then you add 10 to 65 to solve.
X=75 It's solved after dividing 75 to x.
