Question

4.) a parallelogram has one angle that measures 14°, what are the measures of the other three angles in the parallelogram? °, °, and °

Explanation:

Step1: Use opposite angles property

In a parallelogram, opposite angles are equal. So one other angle is $14^\circ$.

Step2: Find adjacent angle measure

Adjacent angles in a parallelogram are supplementary (sum to $180^\circ$).
$180^\circ - 14^\circ = 166^\circ$

Step3: Use opposite angles property again

The angle opposite the $166^\circ$ angle is also $166^\circ$.

Answer:

$14^\circ$, $166^\circ$, and $166^\circ$
