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.
We examine three types: complementary, supplementary, and vertical angles. Definitions: Complementary angles are two angles with a sum of 90Âº. Supplementary angles are two angles with a sum of 180Âº. Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X. In the triangle shown below, the angles A and B are complementary because they have a sum of 90Âº.
