What are the lines that meet to form congruent supplementary angles?
Perpendicular lines.
Supplementary angles form a linear pair?
Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
Can an obtuse triangle have congruent sides?
Yes if it is in the form of an isosceles triangle with the other 2 acute angles being equal
Two adjacent angles that form a line?
Supplementary angles.
What angles together form 180 degrees?
Supplementary angles.
What are the lines that meet to form congruent supplementary angles?
Perpendicular lines.
If two angles are vertical angles then they are congruent?
yes they are because they meet to form at a right angle
Supplementary angles form a linear pair?
Not necessarily. A linear pair of angles must be supplementary but supplementary angles need not form a linear pair. For example, the opposite angles of a cyclic quadrilateral are supplementary but they are (by definition) not next to one another.
Can an obtuse triangle have congruent sides?
Yes if it is in the form of an isosceles triangle with the other 2 acute angles being equal
What are two right angles?
They would be called "supplementary angles" because 90º + 90º = 180º and any two angles that add to 180º form straight, parallel, or congruent lines.(Angles that add to 90 º are called complementary.)
Two angles that form a straight line?
Supplementary angles.
If two angles form a linear pair?
If they do , the angles are supplementary !
Two adjacent angles that form a line?
Supplementary angles.
What angles together form 180 degrees?
Supplementary angles.
Which are the two adjacent angles which are supplementary form what?
Supplementary adjacent angles add up to 180 degrees
What is the pair of congruent angles that form one of the bases of an isosceles trapezoid?
They are congruent angles.
If two angles are supplementary to the same angles then?
they form a straight line
