Divide the trapezium into two parts such that they can be reassembled to make a triangle
In a square \(ABHI\) two smaller squares are drawn: \(ACFG\) with area equal to \(16\) and \(BCED\) with area equal to \(4\). Find the area of hexagon \(DEFGIH\).
If each of the small squares has an area of \(1\), what is the area of the triangle?
Divide the parallelogram into two parts such that they can be reassembled to make a triangle.
Cut a triangle into three parts, which can be reassembled into a rectangle.
On the diagram each number denotes the area of a rectangle it is written into. What are the areas of the other rectangles?
Draw any quadrilateral with all sides of different length and divide it into \(5\) polygons of equal area.
Line \(AB\) is parallel to line \(CD\) and line \(AD\) is parallel to line \(BE\). Show that triangles \(ADE\) and \(ABC\) have equal areas.
A quadrilateral \(ABCD\) is given. Points K and L belong to the side \(AB\) and \(AK=KL=LB\) and points \(N\) and \(M\) belong to the side \(CD\) and \(CM=MN=ND\). Show that the area of the quadrilateral \(KLMN\) is \(\frac13\) of the area of the quadrilateral \(ABCD\).
