You do not set them. If they are formed by two parallel lines and an intercept in a plane, then they are. They are even if you never even see them to set them.

If two angle measure up to 112 and 36 what will the other one be?

If this for triangle then the other angle would be 32o Sum of interior angles of a triangle = 180o Therefore your question would be 180 - (112 + 36) = This would equal the other angle


What is the measure of the interior angle if its exterior angle is 140 degrees?

40 degress because a straight line is 180 degrees and an interior angle with its exterioir angle is a line spilt in half so to find the interior/exterior angle, taek 180 and subtract the interior/ exterior angle and then you will get the the other angle, sorry this is kinda conufsing!


What is one interior angle of a nonagon?

Any angle between 0 and 360 degrees. An interior angle of any polygon (other than a triangle) can have any value in that range.


What is an isosoceles triangle?

An isosceles triangle is a triangle with two equal sides and two equal angles. The two equal sides are called the legs, and the angle between them is called the vertex angle. The two other angles in an isosceles triangle are equal and are called the base angles.


What is the measure of one of the exterior angles of regular pentagon?

Mathematically - A regular pentagon has interior angles and sides equal. Bisecting each interior angle and extending a line segment to the center gives you five equal angles (360o/5=72o). Using the triangle formed by two line segements and a side of the pentagon we know the sum of interior angles of each triangle equals (180o) and we know one angle is 72o. The sum the other two interior angles of each triangle equals (180o-72o=108o) which equals each interior angle of the pentagon (equal to the sum of these two angles). Thus the exterior angle of each corner of the pentagon equals (360o-108o=252o). :-)


How do you find the interior angle of a 9-gon?

The interior angle of any polygon (other than a triangle) can have ANY value greater than 0 degrees and less than 360 degrees. 180 degrees may be excluded since that does not really make an angle. There is no other requirement of an individual angle. Consequently, you cannot find an interior angle of a 9-gon.


If the vertex angle of an isosceles triangle has a measure of 108 what is the base angle?

In an isosceles triangle two of the sides are equal, as well as two of the angles. Because a triangle's interior angles add up to 180, only one angle could be 108, therefore the other two angle must be equal. To find the measure of the other two angles 180 - 108 = 72/2 = 36.
