Given: RW ≅ WT; UW ≅ WS Prove: RSTU is a parallelogram.

Quadrilateral R S T U is shown. Diagonals are drawn from point S to point U and from point R to point T and intersect at point W. The lengths of S W and W U are congruent. The lengths of R W and W R are congruent.

Identify the steps that complete the proof.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
