(a)
To find: whether the statement is true or false.
(a)

Answer to Problem 1MRE
The given statement is true.
Explanation of Solution
Given:
The statement is given as “If two lines are perpendicular, then they form congruent adjacent
Calculation:
Consider the statement.
If two lines are perpendicular, then they form congruent adjacent angles.
Adjacent angles are angles that come out of the same vertex. Vertical angles are always congruent, which means that they are equal.
When two lines are perpendicular, then they form four angles each measuring
Therefore, the given statement is true.
(b)
To find: the converse of the given statement.
(b)

Answer to Problem 1MRE
If two lines intersect to form congruent adjacent angles, then the lines are perpendicular.
Explanation of Solution
Given:
The converse of the statement is “If two lines intersect to form congruent adjacent angles, then the lines are perpendicular”.
Calculation:
Consider the statement.
“If two lines are perpendicular, then they form congruent adjacent angles”.
Recall that the converse of a statement “if p, then q” is given as “if q, then p”.
So, the converse of the given statement is,
“If two lines intersect to form congruent adjacent angles, then the lines are perpendicular”.
(c)
To find: whether the converse of the statement is true or false.
(c)

Answer to Problem 1MRE
The converse statement is true.
Explanation of Solution
Given:
The converse of the statement is “If two lines intersect to form congruent adjacent angles, then the lines are perpendicular”.
Calculation:
Consider the statement.
If two lines are perpendicular, then they form congruent adjacent angles.
The converse of the statement is,
“If two lines intersect to form congruent adjacent angles, then the lines are perpendicular”.
The sum of all the angles when two intersect is
Therefore, the converse of the statement is true.
