Yes, it can always be divided in 2 triangles.
This is because every quadrilateral has 2 diagonals. It is these diagonals that divide the quadrilateral into 2 triangles.
Yes, two equal right-angle triangles.
Infinitely many. Any triangle inside a quadrilateral can be divided into two without affecting the quadrilateral but increasing the number of triangles by 1. And then one of those triangles could be spilt into two and so on - without end.
If it is in the form of two inverted triangles, then there are 8 triangles. If only the outline is used, there are 0 triangles.
The four quadrilaterals that are symmetrical and have two pairs of parallel sides are:SquareRectangleRhombusParallelogram
Yes
Yes
Not true because all quadrilaterals contain 2 triangles
You will either get two triangles, two rectangles, or two irregular quadrilaterals.
Polygon
Trapezoid
No matter the form a four sided shape can always be divided into two triangles with a single line.
They are called polygons
You would get two scalene triangles.
A quadrilateral equals 360 degrees because it can be divided into two triangles. Each triangle has an angle sum of 180 degrees, so when you add the angles of the two triangles together (180 + 180), you get 360 degrees. This property holds for all quadrilaterals, regardless of their shape.
There are two types of quadrilaterals that are formed when two congruent equilateral triangles are joined. These shapes are rhombus and parallelogram.
To join triangles to make quadrilaterals, you can align two triangles along one of their edges, ensuring that the edges match perfectly. By combining the two triangles this way, their adjacent sides form a new quadrilateral. You can also use multiple triangles, ensuring that their edges continue to align to create a closed four-sided shape. Experimenting with different triangle orientations can yield various quadrilateral shapes.
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
