What makes a pair of angles vertical angles?
Vertical angles occur when 2 angles are directly across from each other and are congruent.
Can 2 right angles form a linear pair?
yes!
Can 2 supplementary angles also be a linear pair?
totaly
Can 2 obtuse angles form a linear pair?
No, they cannot.
What are vertivle angles?
I think you mean vertical angles. Vertical angles are formed by two intersecting lines that make what looks like an X. Vertical angles are the two angles that are across from each other, either the top and bottom 2 angles or the left and right 2 angles. Vertical angles are also always congruent!
What is the difference between a linear pair and vertical angles?
In a Linear Pair the 2 angles add up to 180 degrees while Vertical Angles are just 2 vertical angles that are congruent.
which of the following reasons can be used for statement 2 of the proof?
vertical angles theorem
Are 2 angles a linear pair?

Are 2 linear pair 2 angles that dont touch each other?
No. A linear pair is formed by a line (hence linear) with one point on the line having a ray which does not match either part of the line. This forms a linear pair, 2 angles with the ray as a common side, so they do 'touch.'
What is the linear pair postulate?
1. Where the angles in a linear pair are supplementry, and if parallel lines are cut by a transversal, then the interior angles are congruent, and if two lines are cut by a transversal so that a pair of alternate interior angles are congruent, then the two lines are parallel. That's what makes up a linear pair postulate anyway. 2. If two adjacent angle's unshared sides form a straight angle, then they are a linear pair. 3.If two angles form a linear pair,then they are supplementary.
Are all linear pairs supplementary angles?
supplementary can sure be a linear pair. As long as their is 2 different angles and they equal 180 degrees.
What is a pair of angles with the same measurement formed by 2 intersecting lines?
The math name for this is vertical angles.
What is a counterexample for all intersecting lines form right angles?
Say angle 1 is 40 which means that if angle 3 is congruent then angle 3 is also 40 by definition of vertical angles. That would make angle 2 equal to 140 by definition of a linear pair and so angle 4 is congruent by vertical angles.
