Yes. For example, a quadrilateral with internal angles of 80, 80, 80, 120 has three congruent angles, but is not a rectangle.

Does a quadrilateral have three congruent angles?
It cannot. There is no way to draw a quadrilateral where 3 sides are congruent.
Does a quadrilaters have exactly three congruent angles?
Not sure what a "quadrilaters" is. A quadrilateral is a plane (2-dimensional) figure with four straight sides. It can have all four angles different. It can have two congruent angles (kite), 3 congruent angles (no specific name), 2 pair of two congruent angles (parallelogram/rhombus), or four congruent angles (rectangle/square).
What quadrilateral always has 3 congruent angles?
triangle
Do a quadrilateral always have exactly two congruent angles?
No. Only sometimes. A quadrilateral can have any number of congruent angles ... none, 2, 3, or 4.
Does a quadrilateral have exactly 3 congruent angles?
A quadrilateral is ANY closed figure with 4 sides. Therefore, it also has 4 angles - any of which may, or may not, be congruent. About the only general statement about angles that applies to all quadrilaterals is that the sum of the angles is 360 degrees. By the way, it is possible for a quadrilateral to have 3 congruent angles, and the fourth angle not be congruent with the other 3.
Does a quadrilateral always have exactly three congruent angles?
A quadrilateral never has exactly 3 congruent angles. It can have none, two, two pairs of two, or four.
Does a quadrilateral always have 3 congruent angles?
No. Very few of them do.
How many acute angles are there in a quadrilateral that is not a rectangle?
3
Does a quadrilateral triangle have exactly 3 congruent angles?
A quadrilateral shape has four sides and four internal angles. A triangle has three sides and three internal angles. Therefore there is no such thing as a quadrilateral triangle.
Is a triangle and rectangle congruent?
No, a triangle and a rectangle are not congruent. Congruent means exactly the same size and shape. A triangle has 3 sides while a rectangle has four. A triangle's three angles always add up to 180 degrees where as a rectangle's four right angles always equal 360 degrees. They are not congruent- not even similar- at all.
3 things unique about a rectangle?
It is a parallelogram with 4 right angles and it has congruent diagonals that bisect.
Does a quadrilateral triangle have exactly 2 congruent angles?
Quadrilaterals are not triangles, and there is no such thing as a quadrilateral triangle. Perhaps you mean equilateral, in which case, it has 3 equal angles and 3 equal sides; the word equilateral actually means equal sides. And quadrilateral means four sides. Triangle means 3 angles.
