Do all squares have two pairs of parallel sides? explan

Yes any square is also a parallelogram, but not the other way around (some parallelograms are not squares). In other words, any square is a parallelogram.

If you draw a Venn Diagram, the set of squares will be entirely inside the set of parallelograms.

This is because any rhombus is also a parallelogram, and the same applies to rectangles as well. A square is the combination of a rhombus and rectangle.

Rhombus = four sided figure where all sides are equal

Rectangle = four sided figure where all angles are equal to 90 degrees

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
