angles

The last 2 weeks we have been doing angels. There are 6 types of angels that you have to know they are called acute angles and an acute angle is less than 90 degrees and more than 0 degrees. A right angles is 90 degrees. An obtuse angle is more than 90 degrees and less  than 180 degrees. An straight line is 180 degrees. An relex is more than 180 degrees and less than 360 degrees. And revelation is 360 degrees. We measured angles with a protractor. a protractor is a plastic, transparent, and its a semi circle but sometimes it can be a full circle. The semi circle one measures up to 180 degrees but a full circle protractor measures up to 360 degrees. And it helps us do angles. yesterday we were still doing angles but we were doing complementary angles and supplementary angles. A complementary angle is a angles that adds up to 90 degrees and a supplementary angle is a angles that adds up to 180 degrees.
