The corner of the cement cinder
block represents Quadrant 3 of
the unit circle if a circle was placed
directly over it. Also shows degree
angle of 90 degees with 90 degrees
rt/2, Also symbolizes a right

A clock virtually symbolizes the
entire unit circle. Each corresponding
angle on the clock has a relative
measurement in time or degree. This
is so with the unit circle of rt as well.

This table simple represents
symbolically the shape of the unit
circle, Though thereis no numerical
value associated on the surface, but
the shape is equal tori=360 degees
or 2n.

The angle of the rail is equivalent to
the 240 degree mark, or more so the
210 degree from the unit circle. (-3/
