WebThe top line (that touches the top of the triangle) is running parallel to the base of the triangle. Notice that: angles A are the same; angles B are the same; And you can see that A + C + B rotates from one side of the straight line to the other, or a full 180° Web(Note: "Degree" is also used for Temperature, but here we talk about Angles) The Degree Symbol ° We use a little circle ° following the number to mean degrees. For example 90° means 90 degrees. One Degree. This is how large 1 Degree is. The Full Circle. A Full Circle is 360° Half a circle is 180° (called a Straight Angle) Quarter of a ...
