The compass is used to measure angles. The straightedge is used to draw a straight line. The two items together, are used to measure and draw angles and lines in geometric drawings.

Angles are measured in degrees, minutes and seconds A full rotation measures 360 degrees
A congruent triangle is a triangle that has the same size and shape as another triangle. This means that all corresponding sides and angles of the triangles are equal. Congruent triangles can be identified in geometric figures by comparing the lengths of their sides and the measures of their angles to see if they match up exactly.
The only thing that can contain all geometric figures is the set of all geometric figures, which is an infinite set.
