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 said to be complementary when the sum of the two angles is 90Â°. Two angles are said to be supplementary when the sum of the two angles is 180Â°. If we have two parallel lines and have a third line that crosses them as in the ficture below-the crossing line is called a transversal. When a transversal intersects with two parallel lines eight angles are produced. The eight angles will together form four pairs of corresponding angles.
