Why do parallel lines always make vertical angles?
Wrong statement. Parallel lines don't always make vertical angles without the transversal, the line that passes through these lines. Without the transversal, we can't make the conclusion that parallel lines form vertical angles.
What could be a valid conclusion from the following given statement If two angles are supplementary then the sum of their measures is 180 are supplementary?
A valid conclusion would be that a tautology is true.
What are all of the situations in which the statement Two vertical angles are supplementary is true?
If the lines are perpindicular then each pair of vertical angles are supplementary
which statement is missing from the following proof theorem: vertical angles are congruent.?
A+
If two angles are vertical then what are they?
If two angles are vertical then they are congruent.
Can two vertical angles have measures of 54deg and 60deg?
no vertical angles are equal
Do vertical angels have the same measures?
Yes, vertical angles do have the same measures.

What could be a valid conclusion from the following given statement If two angles are supplementary then the sum of their measures is 180 are supplementary?
A valid conclusion would be that a tautology is true.
Are angles whose measures have a sum of 90 percent?
Vertical angles
Is It true that angles whose measures are equal are vertical angles?
true
Are 2 angles whose measures have a sum of 90 percent?
Vertical angles
is this biconditional true or falseTwo angles are vertical angles if and only if their measures are equal.?
false
What is a counter example for the statement congruent angles are always vertical angles?
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
What are all of the situations in which the statement Two vertical angles are supplementary is true?
If the lines are perpindicular then each pair of vertical angles are supplementary
What do you notice about the measures of pairs of vertical angles?
they are congruent: exactly equal
which statement is missing from the following proof theorem: vertical angles are congruent.?
A+
