A right angle triangle has one 90 true or false?
True. It could not have 2 right angles, because the combined angles of a triangle equal 180 and 2 right angles would leave the final side at 0 degrees.
Is true the supplementary angles are always adjacent?
Sometimes but not always depending on what type of polygon it is and supplementary angles add up to 180 degrees
The measures of two adjacent interior angles sum to 180 because they form a linear pair?
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
How do you find the measures of the remaining three angles of a parallelogram if you already know the measure of one of the angles?
The opposite angle is the same as the known angle. Each of the adjacent angles is the supplementary angle to the known angle. That is the pair add up to 180 degrees.
Given mm plus mu equals 180 wfmu must be a parallelogram true or false?
True
A right angle triangle has one 90 true or false?
True. It could not have 2 right angles, because the combined angles of a triangle equal 180 and 2 right angles would leave the final side at 0 degrees.
Is the sum of the interior angles a triangle will always be 180 true or false?
True the 3 interior angles of any triangle always add up to 180 degrees
What is the sum of adjacent angles in a parallelogram?
180
In a parallelogram consecutive angles are always?
In a parallelogram consecutive angles are always supplementary. This means they equal 180.
Does a parallelogram have reflex angle?
No. In a parallelogram, adjacent angles are supplementary (they add up to 180°). A reflex angle is between 180° and 360°. So if one of the angles could be greater than 180°, then the adjacent angle would have to be negative, or else it is not a parallelogram. * * * * * All the EXTERNAL angles of a parallelogram are reflex angles!
What are the names of the angles in the parallelogram?
180 degrees i believe
Parallelogram consecutive angles conjecture?
The Parallelogram Consecutive Angles Conjecture states that the consecutive angles in a parallelogram are supplementary. This means that the sum of two adjacent angles in a parallelogram is always 180 degrees. This property follows from the fact that opposite angles in a parallelogram are congruent.
Is it true that measures of two adjacent interior angles sum to 180 because they form a linear pair?
only in a parallelogram
Are the top angles in a parallelogram equal to 180 degrees?
Yes.
Do the opposite angles of a parallelogram add up to 180 degrees?
No.
Are all angles of a parallelogram equal to 90 degrees?
No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).
