Answer to Problem 5WE
Explanation of Solution
Given:
The diagram:
Concept Used:
Theorem 3-3: Same side of interior
Theorem 5-1: opposite sides of parallelogram are equal to each other
Theorem 5-2: Parallelogram’s opposite angles are equal.
Consider the figure shown below:
Here it is given that
So, by theorem 5-1, its opposite sides are congruent.
Here
Thus,
And
Also by theorem 5-2, opposite angle of parallelogram
That is,
Now, both pair of opposite sides of a parallelogram are parallel. So,
