A straight line can intersect the side of a convex quadrilateral in at most two points and so divided it into at most two segments. A concave quadrilateral (an arrowhed or chevron) can be divided into three if the line touches the reflex vertex and cuts off the two "barbs" of the arrowhead. But 4 triangles is not possible.
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.
50% because a trapezoid is made from 2 triangles
Put the triangles in a line alternately pointing up and down.
To create two right triangles and an isosceles trapezoid by drawing two straight lines through a square, draw one line to be one of the diagonals of the square. Draw the other line parallel to the first. The three pieces shown are two right triangles and an isosceles trapezoid.
draw two triangles with overlapping lines

If you accept that the sum of the angles in a triangle is 180 degrees, then picture this. A quadrilateral shape is two triangles. If you draw a line between one pair of opposite corners in quadrilateral shape, you have two triangles that share a common side. The sum of the angles in the quadrilateral must equal the sum of the angles in the two triangles. 2 x 180 = 360
A quadrilateral is any plane figure bounded by four straight lines. If a line is drawn from one corner to the opposite corner of a quadrilateral then it is divides the quadrilateral into two triangles. As the sum of the angles of a triangle is 180° then the sum of the internal angles of a quadrilateral total 360°. Special forms of a quadrilateral are :- Parallelogram, Rhombus. Rectangle, Square, Trapezoid / Trapezium and Kite.
Yes, of course. Just draw a line from one corner to its adjacent corner. (The one not directly attached to the first corner.)
draw a straight line then draw a circle on that line at the top then draw a swirl in the circle
There are 16 possible triangles.
you can use a ruler or a book or anything that has a straight line
