Answer :
Step-by-step explanation:
a. True
Draw a right angle.
Now draw a ray in the interior of the angle with the ray starting at the vertex of the right angle. Inside the right angle there are two complementary adjacent angles.
b. True
Draw two perpendicular lines. Each of the 4 angles formed measures 90°. Each pair of vertical angles has a sum of measures of 180°, so each pair of vertical angles is supplementary.
c. False
The sum of the measures of two complementary angles is 90°. The sum of the measures of two supplementary angles is 180°. The sum of two numbers cannot be both 90 and 180.
