Show that each statement is false by providing a counterexample.
(a) If 21 and 22 are complementary angles, then one of them must have a
measure less than 45°.
Counterexample: m1 =
(b) If the measures of R, S, and I sum to 180°, then one of the angles must
be obtuse.
m42 =
Counterexample: m 2R =
.m4S = [], m (c) If m2 WXZ = 34°, and point Y is in the interior of WXZ, then mWXY = 17°
and mYXZ = 17%.
Counterexample: m2 WXY =
Counterexample: length =
₁mYXZ =
(d) If the perimeter of a rectangle is 28, then the length is 10 and the width is 4.
width = 0
