Say True or False:
(a) The measure of an acute angle $ <90^{\circ} $.
(b) The measure of an obtuse angle $ <90^{\circ} $.
(c) The measure of a reflex angle $ >180^{\circ} $.
(d) The measure of one complete revolution $ =360^{\circ} $.
(e) If $m \angle A = 53^o$ and $m \angle B = 35^o$, then $m \angle A > m \angle B$.

To do:

We have to find whether the given statements are true or false.
Solution:

(a) The measure of an acute angle is less than $90^o$

Therefore, the given statement is true.

(b) The measure of an obtuse angle is more than $90^o$ but less than $180^o$

Therefore, the given statement is false.

(c) The measure of a reflex angle is more than $180^o$.

Therefore, the given statement is true.

(d) The measure of one complete revolution is $360^o$

Therefore, the given statement is true.

(e) $53^o>35^o$

This implies,

$m \angle A > m \angle B$

Therefore, the given statement is true.
