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.
Supplementary angles: Two angles who measures have a sum of 180. and KMH are complementary because they add up to 180 degrees, which is a straight line. is a straight line. Although not pictured, supplementary angles do not need to be adjacent. Vertical angles: Two angles whose sides are opposite rays. The vertical (opposite) angles are congruent. The example below shows two sets of vertical angles, 1 and 3, 2 and 4.
