Spiral Review:
The figure shown is a parallelogram with line segments drawn
between each pair of parallel sides. The angles formed where the
line segments intersect are numbered 1 to 4 . Use the figure to
answer the questions.
Part A: What is the sum of the measures of angles 1 and 2 ? Exp
your answer.

In a parallelogram, opposite angles are equal and adjacent angles are supplementary, meaning they sum to 180 degrees. Therefore, angles 1 and 2 are adjacent angles formed by the intersection of a transversal with the parallel sides. This means that their measures add up to 180 degrees, so the answer to the question is 180 degrees.

Now, here’s a little fun fact: if you ever find yourself in a geometry party (which honestly sounds like a blast!), just remember that the area of a parallelogram is calculated as base times height—a classic formula that never lets you down! It’s like the trusty party trick for impressing math lovers everywhere!
