Hi! We're Ms. Wyatt's 6th Grade class from McKinley Elementary
in Middletown, Ohio. In Mr. Harris' math class today, our group
solved Polygon #2. Here is our solution:
A rhombus with sides of 4.5 cm. and one diagonal of
4.5 cm. and the other diagonal is 7.8 cm. (rounded to the nearest
tenth.)
First, we used the characteristic clues to eliminate
possible solutions. It was either a square or a rhombus. Second, we
knew it could not be a rhombus because of the diagonal of 4.5 cm. It had to
be a rhombus. Finally, Mr. Harris helped us to find the other
diagonal by using the Pythagorean Theorem.
