Examples and exercises with solutions of plane angle
Exercise #1
True or false?
One of the angles in a rectangle may be an acute angle.
Video Solution
Step-by-Step Solution
One of the properties of a rectangle is that all its angles are right angles.
Therefore, it is not possible for an angle to be acute, that is, less than 90 degrees.
Answer
False
Exercise #2
If the two adjacent angles are not equal to each other, then one of them is obtuse and the other acute.
