Division of Plant Sciences. A terrarium is a tightly closed, clear glass or plastic container filled with small plants (Figure 1). It also has come to mean an open, transparent container for growing and displaying plants. Terrariums are most useful for small plants that do not adapt well to normal home atmospheres.ivision of Plant Sciences.

The S in supplementary can be used to form the 8 in 180. The C in complementary can be used to form the 9 in 90. If we know that a set of angles form one of these special relationships, we can determine the measure of the other angle. Example #1: 43Â°. To determine the supplement, subtract the given angle from 180.
Two Angles are Supplementary when they add up to 180 degrees. These two angles (140Â° and 40Â°) are Supplementary Angles, because they add up to 180Â°: Notice that together they make a straight angle. But the angles don't have to be together.
