A woodworker uses a caliper to measure the
widths of a bat to help him determine the
widths for a new bat. The woodworker places
the open tips of the caliper on the bat. The
distance between the tips is a width of the bat.
A. Suppose a caliper opens to an angle of 25?º
for one width of a bat and opens to an angle of
35? for another. What can you conclude about
the widths of the bat?
acute angle
B. Use Patterns and Structure Next, suppose you
use a caliper to measure the width of a narrow
part of a bat and a wider part of the bat. What
can you predict about the angle to which the
caliper opens each time?
