Is kites each diagonal divides the given quadrilateral into two congruent triangles?
Yes
Why the area of a triangle is half the area of a quadrilateral?
The area of a triangle is half the area of a quadrilateral when the quadrilateral is divided into two triangles by drawing a diagonal. Since both triangles share the same base and height (the height being perpendicular to the base), the area of each triangle is equal to half the area of the quadrilateral. Therefore, for any quadrilateral, its area is double that of each of the triangles formed by its diagonal.
What Quadrilateral that has two lines of symmetry that are diagonals?
The quadrilateral that has two lines of symmetry that are diagonals is a rhombus. In a rhombus, the diagonals bisect each other at right angles and serve as lines of symmetry. Each diagonal divides the rhombus into two congruent triangles, reflecting the shape across the diagonal. This property gives the rhombus its two lines of symmetry.
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.

Diagonal of parallelogram divides it into four triangles?
When a diagonal is drawn in a parallelogram, it splits the shape into two congruent triangles. Each of these triangles is further divided by the other diagonal, resulting in a total of four smaller triangles within the parallelogram. These triangles are all formed by the intersection of the diagonals and the vertices of the parallelogram. As a result, the diagonal effectively segments the parallelogram into four distinct triangular areas.

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.

Each diagonal divides the rhombus into two congruent triangles, reflecting the shape across the diagonal. This property gives the rhombus its two lines of symmetry.
The sum of interior angles of a square is?
360 degrees. Same for any other rectangle, rhombus, parallelogram, or convex quadrilateral. The reason is that any quadrilateral can be divided into two triangles by drawing a diagonal and the sum of the angles of each triangle is 180 degrees.

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 one pair of opposite angles and one pair of opposite sites of a quadrilateral is congruent then the quadrilateral is a parallelogram. How can it be proven?
draw a diagonal through opposite corners of the quadrilateral. This makes two triangles. Prove the triangles are congruent using SSA (side side angle) congruence. Then show that the other two sides of the quadrilater must be congruent to each other, so it is a parallelogram.
Diagonal of parallelogram divides it into four triangles?
When a diagonal is drawn in a parallelogram, it splits the shape into two congruent triangles. Each of these triangles is further divided by the other diagonal, resulting in a total of four smaller triangles within the parallelogram.

As a result, the diagonal effectively segments the parallelogram into four distinct triangular areas.
How do you make four triangles out of a quadrilateral by a line through it?
You cannot make four triangles our of a quadrilateral by ONE line through it. One line can give you at most two triangles. Two lines, each running from one vertex of the quadrilateral to the opposite vertex, will give 4 triangles.
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.
Why the sum of the interior angles of any quadrilateral is always 360?
The sum of the interior angles of any quadrilateral is always 360 degrees because a quadrilateral can be divided into two triangles by drawing a diagonal. Each triangle has interior angles that sum to 180 degrees, so when you add the angles of the two triangles together (180 + 180), you get a total of 360 degrees. This property holds true for all quadrilaterals, regardless of their shape.
Use six toothpicks to construct four congruent triangles?
Arrange the toothpicks to form a square with a diagonal crossing through the center. Then, create triangles by connecting each corner of the square to the center of the diagonal. Each of the four resulting triangles will be congruent to each other.
