How determine whether the conjecture is true or false. If false give a counterexample. Given LMN and XMZ are coplanar. Conjecture The angles are vertical angles.?
Select one: a. False; the angles may be supplementary. b. True c. False; one angle may be in the interior of the other. d. False; the angles may be adjacent.
The measrues of two adjacent interior angles sum 180 because they form a linear pair?
False.
The measures of an exterior angles and the adjacent interior angle sum to 360 degrees because they from a linear pair?
False. apexs
Is a vertical line of 0 true or false?
False
Supplementary angles add to 270 degrees true or false?
False. Supplementary angles add to 180degrees.
A pair of vertical angles are acute true or false?
Sometimes

Select one: a. False; the angles may be supplementary. b. True c. False; one angle may be in the interior of the other. d. False; the angles may be adjacent.
Do vertical angles have the same vertex?
Yes, since the vertex is a point and the vertical angles share that point.
True or false two vertical angles may also be complementary?
False
Do the angles that form a linear pair have to be adjacent?
The measures of two adjacent interior angles sum to 180 because they form a linear pair.B. False
Are Adjacent angles of a quadrilateral in a circumscribed circle are always supplementary?
False :]
is this biconditional true or falseTwo angles are vertical angles if and only if their measures are equal.?
false
Intersecting chords form a pair of supplementary vertical angles?
false
The measures of two adjacent interior angles sum to 180 because they form a linear pair?
false
The measrues of two adjacent interior angles sum 180 because they form a linear pair?
False.
Is it true or false supplementary angles are always linear pairs?
True only if the two angles are adjacent (i.e. have a point in common). By definition, supplementary angles add up to 180° therefore they are linear pairs, if they are adjacent. Otherwise false. Imagine drawing an angle of 40° at the top of the page and another of 140° at the bottom. These angles are supplementary but not a linear pair.
If two angles are not vertical then they are not nonadjacent angles formed by two intersecting lines?
False. The angles can be formed by two skew lines intersecting a third line.
