Given the quadilateral:
CATS
We have the figure below:
Let's determine if quadilateral CATS is a parallelohram.
A parallleloram is a quadilateral that has two pairs of parallel sides with opposite equal sides.
The opposite sides of a parallelogram are equal.
The diagonals of a parallelogram are not of equal length.
Thus, we have:
Line CA is parallel to line ST ==> CA||ST
LIne SC is parallel to lne TA ==> SC||TA
Line SC is equal to line TA ===> SC = TA
Line CA is equal to line ST. ==> CA = ST
Therefore, the set of information that can be used to conclude that quadilateral CATS is a prallelogram is:
CA||ST and SC = AT
ANSWER:
CA||ST and SC = AT
