Need fast! ron claims that the opposite sides of a quadrilateral are always congruent. which quadrilateral could be used to show that ron's claim is false? a. non-square rectangle b. parallelogram c. rhombus d. trapezoid

(D)

Step-by-step explanation:

A quadrilateral is a 4 sided figure.

According to question, Ron claims that the opposite sides of a quadrilateral are always congruent. Congruent sides means the sides which are exactly equal in length and size.

A non-square, a parallelogram and a rhombus has both pair of opposite sides congruent.

But in trapezoid, the opposite sides are not congruent.

Option (D) could be used to prove that Ron's claim is false.

step-by-step explanation:

abc

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.
