a.
To plot the given points and draw the quadrilateral ABCD and its diagonals and then tell which of the following statements are true for quadrilateral ABCD .
a.

Answer to Problem 2E
True statements: I, II, III, IV, V
Explanation of Solution
Given:
Coordinates of the vertices of quadrilateral ABCD : A(1,2) , B(−3,−1) , C(−7,2) , D(−3,5)
Given statements:
- Quadrilateral ABCDis parallelogram.
- Both pairs of opposite sides are congruent.
- All sides are congruent.
- The diagonals are congruent.
- The diagonals are perpendicular.
- The sides form four right angles.
Plot the given points to draw the quadrilateral ABCD and is diagonals.
A(1,2) , B(−3,−1) , C(−7,2) , D(−3,5)
Conclusion from given statements:
- Quadrilateral ABCD is parallelogram. −True.
From the graph it can be seen that the opposite sides are congruent and parallel. So it is a parallelogram but a special kind of parallelogram which is called rhombus.
- Both pairs of opposite sides are congruent. − True.
From the graph it can be seen that both pairs of opposite sides are congruent.
- All sides are congruent. − True.
From the graph it can be seen that all sides are congruent.
- The diagonals are congruent. − True.
From the graph it can be seen that both the diagonals are congruent.
- The diagonals are perpendicular. − True.
From the graph it can be seen that both the diagonals are perpendicular to each other.
- The sides form four right angles. − False.
From the graph it can be seen that the sides does not form right angles.
Conclusion:
Hence the statements that are true are : I, II, III, IV, V.

Answer to Problem 2E
True statements: I, II, III, V
Explanation of Solution
Given:
Coordinates of the vertices of quadrilateral
B(3,−3)
Given statements:
- Quadrilateral ABCD is parallelogram.
- Both pairs of opposite sides are congruent.
- All sides are congruent.
- The diagonals are congruent.
- The diagonals are perpendicular.
- The sides form four right
angles.
Plot the given points to draw the quadrilateral ABCD and is diagonals.
A(1,1) , B(3,−3) , C(−1,−1) , D(−3,3)
Conclusion from given statements:
- Quadrilateral ABCD is parallelogram. − True.
From the graph it can be seen that the opposite sides are congruent and parallel.
- Both pairs of opposite sides are congruent. − True.
From the graph it can be seen that both pairs of opposite sides are congruent.
- All sides are congruent. − True.
From the graph it can be seen that pairs of opposite sides are congruent and not all sides are congruent.
- The diagonals are congruent. − False.
From the graph it can be seen that both the diagonals are not congruent.
- The diagonals are perpendicular. − True.
From the graph it can be seen that both the diagonals are not perpendicular to each other.
- The sides form four right angles. − False.
From the graph it can be seen that the sides does not form right angles.
Conclusion:
Hence the statements that are true are: I, II, III, V.
