Answer:

B) 8

Step-by-step explanation:

Triangles MNC and RSC are similar because all 3 angles are the same, so the the ratio between each side should be the same.

If NC=12 and SC=6 then triangle MNC is scaled up by 2 from triangle RSC. This means each side of MNC is 2 times bigger than on RSC. So, sense RS=4, we can multiply that by 2 to get MN=8.

<h3>You have the correct answer. It is choice B. Nice work.</h3>

K is the midpoint, so $\overline{IK} \cong \overline{GK}$ and $\overline{JK} \cong \overline{HK}$ , and along with the congruent vertical angles ( $\angle GKH \cong \angle IKJ$ and $\angle GKJ \cong \angle IKH$ ), you would use the SAS (side angle side) congruence theorem to prove the inner pairs of triangles to be congruent.

So, $\triangle HKG \cong \triangle JKI$ (top and bottom triangles) and $\triangle GKJ \cong \triangle IKH$ (left and right triangles).

Then through CPCTC, we can show the corresponding pieces are congruent leading to $\overline{GH} \cong \overline{JI}$ and $\overline{GJ} \cong \overline{HI}$ showing the opposite sides of the quadrilateral are congruent. Therefore we do have a parallelogram and enough information to prove it as such.
