“Why are there 360 degrees in a circle?” A regular reader recently asked me that question. My first response was to say “Because Miss Helland told me so.” Miss Helland was my high school teacher for ...

The angle at the circumference in a semi-circle is 90°. Angle STU = 90° Angles in a triangle add up to 180°. The angle on a straight line is 180°. The angle VOY = 180°. The angle at the centre is ...
