Question

if (overline{bc}) is not parallel to (overline{ad}), what is (bc?)

Explanation:

Step1: Identify congruent - side property

The figure appears to be a parallelogram (even though it says $BC$ is not parallel to $AD$, the arrow - head markings on opposite sides suggest a mis - statement or mis - labeling as the markings imply parallelism). In a parallelogram, opposite sides are equal.

Step2: Determine the length of $BC$

Since $AD = 72$ and $BC$ is opposite to $AD$, $BC=AD$.

Answer:

72
