Ana has a poster board in the shape of a rectangle. she draws 1 line to cut the poster into 2 new shapes. the 2 new shapes have 7 side and 7 vertices in all. what would the 2 shapes look like?

Triangle(Right angle triangle)

Quadrilateral (Trapzium)

Step-by-step explanation:

Ana has a poster board in the shape of a rectangle.

She draw a line to cut the poster into two new shapes.

The new shapes have 7 sides and seven vertices in all.

She cut from one vertex of rectangle to a point of opposite side of rectangle.

We get two shape one with three side and one with four sides

Therefore, Total side of the two shapes would be  3+4 = 7

Triangle has three vertices and Quadrilateral has four vertices.

Triangle would be right angle triangle.

Quadrilateral would be trapzium.
