Question

Angles, angles everywhere! Big ones, little ones, right

ones too! But this angle is something new. It has two
rays that meet at a vertex, and it measures 180
degrees. How complex! What angle am I? Draw me.

Answer 1

Straight angle

<----------------------------->

You can determine if an angle is a straight angle only if it is 180 degrees. You can also draw it by drawing a straight line and drawing an arrow facing outward at each end.
