It is very possible considering non-closed shapes. For example, picture the letter "M" but drawn into the third dimension, sort of like a open roof gutter (which has 2 corners and 3 sides).
It will have 3 corners and 4 sides (an "L" would have 1 corner and 2 sides).
4 sides and 4 corners because it is a quadrilateral polygon
There is no such shape. If it has two sides meeting, it also has to have a corner. A triangle has three sides and three corners, and a square has four sides and four corners. There is nothing in between.
2 sides, 2 corners. (:
A trapezoid has 4 corners and 4 sides
a quadrilateral
It has 4 corners and 4 sides because it is a quadrilateral polygon
4 corners in a rhombus. Remember that it is a quadrilateral and that quadrilaterals have 4 sides and 4 corners. Quad = Four (4).

A trapezium.
Ah, what a delightful question! A figure with 4 sides and 3 corners is a triangle. Triangles are such lovely shapes, full of balance and harmony. Keep exploring the world of shapes and let your creativity flow like a gentle stream, my friend.
Quadrilateral.
