Teachers, here's a teacher tip, you won't want to miss
2
00:00:03.799 --> 00:00:05.949
when we have a pair of angles on a straight line,
3
00:00:05.960 --> 00:00:09.869
we know they equal 100 and 80 degrees and are known as supplementary angles.
4
00:00:09.880 --> 00:00:12.550
Similarly, when we have a pair of angles on a right angle,
5
00:00:12.560 --> 00:00:16.510
we know it equals 90 degrees and are known as complementary angles.
6
00:00:16.520 --> 00:00:20.270
But how can students remember which is supplementary and which is complementary?

00:00:20.690 --> 00:00:23.420
Here's a handy trick to help them keep it straight.
