Certain kinds of trapezoids only have one pair of equal angles. Like so...

See? The only congruent angles are the two right angles on the left side. (Ignore the dots, it was the only way I could get my diagram to format properly)

What quadrilateral has angles not equal only one pair of parallel sides?
A trapezoid (trapezium) has only 2 sides parallel and not all angles equal
What quadrilateral has 3 equal angles?
There is no specific name for one with 3 equal angles. All the interior angles in a quadrilateral add up to 360°. So you would have 3A + B = 360. Where angles A = C = D. Now a rectangle has 4 equal angles (90°), so it also has 3 equal angles. And just happens to have the 4th angle equal the other 3.To visualize a quadrilateral with only 3 equal angles: take a square ABCD, and stretch angles A,C & D to 91°. Now angle B will equal 87°.
What is an equilateral equiangular quadrilateral called?
It is called a square. The clues: equilateral means all sides are of equal length; equiangular means all angles are of the same degrees; quadrilateral means the shape has four sides. The only shape that qualifies is a rectangle [includes squares.]
What quadrilateral has 4 right angles and 0 equal sides?
I am ONLY 9 but here is my answer.......nothing.
What shape has only 3 angles two of which are equal?
Triangle
If a quadrilateral is a parallelogram will it always have equal angles?
Diagonally opposite pairs of angles will always be equal, but the only time all angles in a quadrilateral parallelogram are equal is when that shape is a rectangle.
What shape has 4 equal sides but the angles are not the same?
There is no four-sided shape (quadrilateral) with four equal sides where no angles are the same. The diagonally-opposing angles must be the same, and opposing sides must be parallel. The only quadrilateral that fits that description is a parallelogram.
What is the name of the Quadrilateral with only right angles?
A quadrilateral is any shape with four sides; angles can be acute or obtuse. A perfect square is the only quadrilateral with only right angles.
Is a kite a regular shape or not a regular shape?
A regular polygon must have all its sides equal and all its angles equal. The only regular quadrilateral is a square.
Does all quadrilaterals angles are the same size?
No, because a quadrilateral can be many different sizes and lengths as a quadrilateral is any shape with only 4 sides. The sum of all the angles in a quadrilateral equal 360 degrees.
What shape has 4 equal sides and only 2 right angles?
There is no quadrilateral that meets these requirements. It is, of course, possible for a pentagon (or polygons with 6 or more sides) to have 4 equal sides and only 2 right angles.
Are squares regular quadrilaterals?
Yes it is a square is a regular quadrilateral because it is not a unknown shape * * * * * That is an interesting reason - but wrong. A square is the only quadrilateral whose sides are all equal and whose angles are all equal. Both sides and angles must be equal for a polygon to be termed regular.
What quadrilateral have adjacent sides not equal two pairs of congruent sides and the little right angles?
A rectangle is the only such shape. Not sure about the "little" right angles: all right angles are of the same measure.
What is the name of the quadrilateral whose angles are equal but only adjacent sides are equal?
Delta
Is the sum of the measures of the angles of a quadrilateral equal to 180 degrees?
No. Only the sum of the measures of the angles of a triangle equal to 180 degrees; in the case of a quadrilateral it amounts to 360 degrees.
What is the quadrilateral with three equal angles?
With quadrilaterals, if there are three equal angles, then we know that the fourth angle must be equal, so the quadrilateral is a rectangle. * * * * * That is absolute rubbish. You can have a quadrilateral with three angles of 70 degrees and the fourth of 150 degrees. There is no name for such quadrilaterals and the only thing that can be said about them is that they are irregular.
What quadrilateral has angles not equal only one pair of parallel sides?
A trapezoid (trapezium) has only 2 sides parallel and not all angles equal
