Question

For the proper construction of a parallelogram, the parameters required are

• A. The length of two adjacent sides and two angles.
  
• B. The measure of the parallel sides.
  
• C. The length of two adjacent sides and one internal angle.
  
• D. The measure of all internal angles.
  

Answer 1

The correct option is C The length of two adjacent sides and one internal angle.


In a parallelogram, the parallel sides are equal. Therefore, knowing the measure of adjacent sides is synonymous with knowing the measure of each side. Also, the two angles in a parallelogram are supplementary to each other. Therefore, if we know one angle, we can find the other.
