How many congruent triangles make a parallelogram?
Answer: 2 Explanation: A parallelogram is a quadrilateral which has both pairs of the opposite sides parallel. Congruent triangles are triangles that have exactly the same three sides and exactly the same three angles. So, in a parallelogram, each diagonal divides it in 2 congruent triangles.

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.
How many congruent sides and angles do equilateral triangles have?
Equilateral triangles have three congruent sides and three congruent angles
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 exactly three congruent angles?
No but an equilateral triangle does.

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.
Does a quadrilateral have 2 congruent angles?
A quadrilateral has four interior angles. It may have two, three, four, or none of them congruent.
Can a quadrilateral have three congruent angles?
Yes.
Does a quadrilateral have three congruent angles?
It cannot. There is no way to draw a quadrilateral where 3 sides are congruent.
Can a quadrilateral with 3 congruent angles not be a rectangle?
Yes. For example, a quadrilateral with internal angles of 80, 80, 80, 120 has three congruent angles, but is not a rectangle.
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).
Does a quadrilateral have exactly three congruent angels?
I think it is a yes
Which type of quadrilateral always has at least three congruent angles?
A rectangle or a square.
