Angles and geometric basics
How it works
A right angle is 90°, a straight angle 180°, and a full angle 360°. Complementary angles can be determined by subtraction. In the coordinate system, x first describes the horizontal, then y the vertical position.
Note
Right angle 90°; straight angle 180°; full angle 360°.
Right angle 90°; straight angle 180°; full angle 360°.
An example
A right angle is divided into 62° and a second angle. How large is the second? Give the result in °.
A right angle is 90°. Remainder=90°−62°. Result: 28 °.
