If three angles of a quadrilateral are congruent and the average of the measures of two angles of the quadrilateral is 80 which number could NOT be the measure of an angle of the quadrilateral?

There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.

Which quadrilateral has opposite sides congruent and 4 right angles but not all congruent?
It seems to measure up to a rectange
What is the measure of each central angle of a quadrilateral?
That depends on the quadrilateral. They will not all have the same measure. Even rectangles will not all have the same central angle measures.
How can knowing two polygons are congruent help you find angle measure of the polygons?
They have the same measures.
What shape is quadrilateral with two pairs of parallel sides and all of the sides are congruent and that none of the angles measure 90 degrees?
A rhombus or diamond.
A quadrilateral with two pairs of parallel sides and four congruent sides is a?
I would say a square because that does have two pairs of parallels sides.All of it's sides are congruent to each other because they all measure 90 degrees.

Quadrilateral with opposite sides and angles equal?
A parallelogram has opposite sides and angles congruent which means of equal measure.
How can knowing two polygons are congruent help you find angle measure of the polygons?
They have the same measures.
What is the measure of a base angle of an isosceles triangle if the vertex angle measures 38 and each of the two congruent sides measures 21 units?
Each of the base angles measure 71 degrees
What is the measure of one of the interior angles of a regular quadrilateral?
Each of the four interior angles of a square (i.e. a regular quadrilateral) measures 90 degrees
What shape is quadrilateral with two pairs of parallel sides and all of the sides are congruent and that none of the angles measure 90 degrees?
A rhombus or diamond.
Two or more angles that have the same measures?
Two or more angles that have the same measure are called congruent angles.
The measures of the three angles of a quadrilateral are 80 140 55 find the measure of the fourth angle?
the angle measures of a quadrilateral must equal 360 degrees so you add 80+140+55=275 then subtract from 360. the answer is 85

What is the measure of a base angle of an isosceles triangle if the vertext angle measures 36 and the two congruent sides each measure 21 units?
(180 - 36) / 2 = 72
