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.
