a. approximately 1\frac{1}{4} inches
b. approximately 1\frac{3}{4} inches
c. approximately \frac{3}{4} of an inch
d. approximately 2 inches
e. approximately 1 inch

Explanation:

• Acute angles can have different measures and are not all congruent. Complementary angles add up to 90 degrees and are not necessarily congruent. Supplementary angles add up to 180 degrees and are not all congruent. Adjacent angles just share a side and a vertex and are not all congruent. Right - angles all measure 90 degrees, so all right angles are congruent.

E. right
