Does the diagonals of a parallelogram bisect the angles?
No, the diagonals of a parallelogram do not necessarily bisect the angles. The diagonals of a parallelogram divide it into four congruent triangles, but they do not necessarily bisect the angles of those triangles.
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.

How are parallelogram related to triangles and rectangles?
If you draw one diagonal across a parallelogram, it will split it into two congruent triangles. A rectangle is a parallelogram, with all four angles equal to 90°.
Is parallelogram can have no congruent angles?
No. In a parallelogram, opposite angles are congruent.
In which parallelogram does the diagonal divide the parallelogram into two congruent right triangles?
It is a rhombus because its diagonals meet at right angles.
Does the diagonals of a parallelogram bisect the angles?
No, the diagonals of a parallelogram do not necessarily bisect the angles. The diagonals of a parallelogram divide it into four congruent triangles, but they do not necessarily bisect the angles of those triangles.

Does a parallelogram have angles that are congruent?
Yes, opposite angles of a parallelogram are congruent.
A quadrilateral has exactly two congruent angles?
A parallelogram has 2 pairs of congruent angles of different sizes
Why are the diagonals of a parallelogram not congruent?
If you look ate the parallelogram you'll see two kinds of triangles. Two that have longer diagonal and bigger angle, and two sides of parallelogram. Then, you have two triangles that have two sides of parallelogram, shorter diagonal and smaller angle. This triangles obviously have two sides that are the same (sides of parallelogram). If this two triangles had been congruent diagonals would have been congruent too, since these triangles would have been congruent. But this is not true unless angles of parallelogram are the same, therefore diagonals cannot be the same length. Of course, there are parallelograms that have same angles, and those are square and rectangle, which do have the same angles. I hope I made this more clear, and I'm sorry for my bad English.
What angles of a parallelogram are congruent?
the opposite angles are congruent
If two triangles have three pairs of congruent angles then the triangles are not guaranteed to be congruent?
Correct. Congruency means that two triangles have three pairs of congruent angles and corresponding sides of the same lengths. A pair of triangles with three pairs of congruent angles but sides of different lengths are similar, not congruent.
What are the properties of the different types of triangle?
There are three types of triangles. Equilateral triangles have three congruent sides and three sixty-degree angles. Isosceles triangles have two congruent sides and the angles opposite those two sides are also congruent. Scalene triangles have no congruent sides or angles.
Can congruent angles determine if there is a parallelogram?
If both pairs of opposite angles of a quadrilateral are congruent, then it is a parallelogram.
