The attachment shows different types of polygons.
Now depending on these we have following five possibilities:
Case 1: Triangle and hexagon
If first polygon is triangle with three angles, the second will have 6 angles and the second polygon will be hexagon.
Case 2: Quadrilateral and heptagon
If first polygon is quadrilateral with 4 angles, the second will have 4+3 =7 angles and the second polygon will be heptagon.
Case 3: Pentagon and Octagon
If first polygon is pentagon with 5 angles, the second will have 5+3=8 angles and the second polygon will be octagon.
Case 4: Hexagon and Nonagon
If first polygon is hexagon with 6 angles, the second will have 6+3=9 angles and the second polygon will be nonagon.
Case 5: Heptagon and Decagon
If first polygon is Heptagon with 7 angles, the second will have 7+3=10 angles and the second polygon will be decagon.
Ellen could be drawing a triangle and a hexagon or a quadrilateral and a heptagon, and so on.
What is a polygon?
A polygon can be defined as a flat or plane, two-dimensional closed shape with straight sides.
We know the polygon with the least number of sides is a triangle.
Suppose Ellen is drawing a triangle.
Since a triangle has 3 angles so polygon with three more angles will be a hexagon.
Suppose Ellen is drawing a quadrilateral.
Since a quadrilateral has 4 angles so polygon with three more angles will be a heptagon.
Suppose Ellen is drawing a pentagon.
Since a pentagon has 5 angles so polygon with three more angles will be an octagon.
Suppose Ellen is drawing a hexagon.
Since a hexagon has 6angles so polygon with three more angles will be a nonagon.
Suppose Ellen is drawing a heptagon.
Since a hexagon has 7angles so polygon with three more angles will be a decagon.
Hence, Ellen could be drawing a triangle and a hexagon or a quadrilateral and a heptagon, and so on.
