True of false angle that forms a linear pair have a sum of 90?
true
True or false a system of two linear inequalities has either no points or infinity many points in a solution?
its true because they have all have the same linear pair It's actually false
The measures of an exterior angle and the adjacent interior angle add up to 180 becvause they from a linear pair true or false?
True
The measure of an exterior angle and the adjacent interior angle sum to 180 because they form a linear pair?
true
Is it true that measures of two adjacent interior angles sum to 180 because they form a linear pair?
only in a parallelogram
Is it always true sometimes true or never true that a pair of vertical angles is a linear pair of angles?
sometime true
If two angles form a linear pair then they are complementary true or false?
A linear pair are always supplementary, 180 degrees not 90.
Is Converse of linear pair theorem true?
No.
True of false angle that forms a linear pair have a sum of 90?
true
Does one of the angles in a linear pair of angles have to be obtuse?
True , but remember there cannot be two obtuse. Must be one acute & one obtuse. * * * * * NOT always true. Both may be right angles.
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 you are asked to solve a system of equations in which there is no linear equation to start with you can sometimes begin by isolating and substituting a variable that is squared in both equations?
true
Intersecting chords form a pair of congruent are they called vertical angles?
apex= True
What is the solution of a system of linear equations in two variables?
The solution of a system of linear equations is a pair of values that make both of the equations true.
True or false a system of two linear inequalities has either no points or infinity many points in a solution?
its true because they have all have the same linear pair It's actually false
The foci of an ellipse will always lie inside the ellipse true or fale?
true
What does it mean for a ordered pair to be a solution to a linear equation?
An ordered pair is a solution only of a linear equation in two variables - not any linear equation. Often the variables are denoted by x and y. If the first of the ordered pair is substituted for x in the equation, and the second for y, then the equation represents a true statement.
