Can you divide a trapezium into two congruent triangles?

No, you cannot.


Why do you think that diagonals bisect each other for proving that a quadrilateral is a parallelogram?

The diagonals divide the quadrilateral into four sections. You can then use the bisection to prove that opposite triangles are congruent (SAS). That can then enable you to show that the alternate angles at the ends of the diagonal are equal and that shows one pair of sides is parallel. Repeat the process with the other pair of triangles to show that the second pair of sides is parallel. A quadrilateral with two pairs of parallel lines is a parallelogram.


How many diagonals are in a quadrilateral?

A diagonal line of a polygon is a line that joins any two vertices not already joined by a side.A polygon with n sides has n(n-3)/2 diagonals→ a quadrilateral with 4 sides has 4(4-3)/2 = 4 × 1 ÷ 2 = 2 diagonalQuadrilaterals include:Squares, rectangles, rhombuses, parallelograms, kites, trapezia (trapezoids).The diagonals of a quadrilateral divide the quadrilateral into 4 triangles. depending upon the quadrilateral some, or all of the triangles may be congruent.The properties of the diagonals of each quadrilateral are:square: equal and bisect each other at 90°; the triangles formed are all congruentrectangle: equal and bisect each other but not at 90°; the triangles formed are all congruentrhombus: not equal but bisect each other at 90°; the triangles formed are all congruentparallelogram: not equal but do bisect each other, but not at 90°; the triangles formed are congruent in (opposite) pairskite: perpendicular and the longer diagonal bisects the shorter diagonal; the triangles formed are congruent in (adjacent) pairstrapezium (trapezoid): only of equal length and bisect each other if it is an isosceles trapezium (trapezoid) and the triangles formed are congruent in (opposite) pairs; otherwise they are of differing lengths and just intersect each others and the triangles formed are non-congruent.


To divide into two congruent parts?

I'm assuming you mean "What does dividing into two congruent parts mean?". It means to divide into two identical halves.


What is the Diagonal of a 24 by 36 foot building?

Pythagoras told us that the hypotenuse of a right triangle equals the square root of the sum of the squares of the other two sides. If you draw a line from corner to opposite corner of your building you divide the floor into two triangles with the same length sides and the hypotenuse is the diagonal of the building. So, taking one of the two triangles the length of the hypotenuse is equal to the square root of 242 + 362 which is 43.27

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 a diagonal of a parralelogram divide a parallelogram into two congruent triangles?

Yes, the diagonal splits the parallelogram into two equal triangle aka congruent the sides will stay the same, the two angles being divided are going to be split in half, one on each side, so its the same


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 can you used a triangle to prove quadrilateral is a parallelogram?

A quadrilateral, in general, is not a parallelogram. If it is a parallelogram then you will have some additional information about its sides and angles. If you do not have such information it is not possible to prove that it is a parallelogram. Draw a diagonal which will divide the quadrilateral into two triangles and use the additional information that you have to show that the triangles are congruent. This can then be used to show equality of sides or of angles: the latter can then be used to show that sides are parallel. Note that the choice of which diagonal may influence how (if at all) you proceed.

How do you divide a square into 2 triangles and 2 trapezoids?

By cutting through its diagonal and cutting off each corner parallel to its diagonal which will leave you with 2 triangles and 2 trapezoids.
