10. Stretch Your Thinking Four angles are put together,
forming a straight angle. Two of the angles are the
same size. The other two angles are also the same
size but different from the other two. If one of the
four angles measures 40°, what are the measures of
the other three angles? Explain.
40°, 50°, 50°; The whole angle is a straight angle,
so the sum of the angles is 180°. One of the
angles is 40°, so another angle is 40° because two
of the angles are the same size. So far, the sum is
40° + 40°, or 80°. So, the other two angles must
measure 180° - 80°, or 100°, altogether. Since
these two angles are the same size, they must be
100° ÷ 2 = 50° each.
