say true or false
(a) the measure of acute angle <90°.
(b) the measure of an obtuse angle <90°
(c) the measure of a reflex angle >180°.
(d) the measure of one complete revolution =360°.
​

Answer 1

Answer:

(a) the measure of acute angle <90°. - True

(b) the measure of an obtuse angle <90° - False

(c) the measure of a reflex angle >180°. - True

(d) the measure of one complete revolution =360°. True

Step-by-step explanation:

(a) Acute angles measure less than 90 degrees.

(b) Obtuse angles measure more than 90 degrees.

(c) A reflex angle is any angle that is more than 180 degrees (half circle) and less than 360 degrees (full circle).

(d) The measure of one complete revolution is 360°.

Answer 2

Answer:

Step-by-step explanation:

Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees.
