What else can I help you with?
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.
Is this statement true or false Two angles that have a common vertex and a common side are called supplementary angles?
False. Two angles that have a common vertex and a common side are called adjacent angles, not supplementary angles. Supplementary angles are two angles whose measures add up to 180 degrees, and they do not necessarily have to share a common side.
The measures of an exterior angles and the adjacent interior angle sum to 360 degrees because they from a linear pair?
False. apexs
True or False Adjacent (or side-by-side) angles of a quadrilateral in a circumscribed circle are always supplementary.?
True. In a quadrilateral inscribed in a circumscribed circle (cyclic quadrilateral), the adjacent angles are always supplementary, meaning their measures add up to 180 degrees. This property arises from the fact that opposite angles subtend arcs that sum to a semicircle. Thus, if one angle is known, its adjacent angle can be determined as 180 degrees minus the known angle.
A pair of vertical angles are acute true or false?

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.
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
Are Adjacent angles of a quadrilateral in a circumscribed circle are always supplementary?
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
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.
