Afor a school project,
students are making a giant
icosahedron, which is a large solid with
many identical triangular faces. john is
assigned quality control. he must make
sure that the measures of all the angles
in all the triangles are the same as each
other. he does this by using a precut
template and comparing the corner
angles of every triangle to the template.
how does this assure that the angles in
all the triangles will be congruent to
each other?
