a)
To find: The statement of theorem 5.1 in IF-THEN form.
a)
Answer to Problem 16CE
Statement of theorem 5.1 in IF-THEN form is written as,” IF a quadrilateral is a parallelogram THEN its opposite sides are congruent.”
Explanation of Solution
Given information: Statements of following theorem is given,
Theorem 5.1: “Opposite sides of a parallelogram are congruent.’
In IF-THEN statement, condition given is written under IF and its result is written under THEN section. So, its formal is, “IF
Thus, the statement of theorem 5.1 should be written as, “IF a quadrilateral is a parallelogram THEN its opposite sides are congruent.”
Conclusion: Thus, above is the required IF-THEN statement equivalent to statement of theorem 5.1.
b)
To find: The statement of theorem 5.2 in IF-THEN form.
b)
Answer to Problem 16CE
Statement of theorem 5.2 in IF-THEN form is written as,” IF a quadrilateral is a parallelogram THEN its opposite
Explanation of Solution
Given information: Statements of following theorem is given,
Theorem 5.2: “Opposite angles of a parallelogram are congruent.’
In IF-THEN statement, condition given is written under IF and its result is written under THEN section. So, its formal is, “IF
Thus, the statement of theorem 5.2 should be written as, “IF a quadrilateral is a parallelogram THEN its opposite angles are congruent.”
Conclusion: Thus, above is the required IF-THEN statement equivalent to statement of theorem 5.2.
c)
To find: The statement of theorem 5.3 in IF-THEN form.
c)
Answer to Problem 16CE
Statement of theorem 5.3 in IF-THEN form is written as,” IF a quadrilateral is a parallelogram THEN its diagonals bisect each other.”
Explanation of Solution
Given information: Statements of following theorem is given,
Theorem 5.3: ”Diagonals of a parallelogram bisect each other.”
In IF-THEN statement, condition given is written under IF and its result is written under THEN section. So, its formal is, “IF
Thus, the statement of theorem 5.3 should be written as, “IF a quadrilateral is a parallelogram THEN its diagonals bisect each other.”
Conclusion: Thus, above is the required IF-THEN statement equivalent to statement of theorem 5.3.
