“If the opposite sides of quadrilateral are equal and parallel, then the quadrilateral is a parallelogram”.
Explanation of Solution
Given information:
Given figure,
Given:
Calculation:
From the figure note that,
It is required to state the principal definition or theorem that proves the quadrilateral
From the above, one can note the opposite sides of the quadrilateral
Therefore, the required theorem is,

- Mariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward20arrow_forward
