odd geometric shapes and the calculation/manipulation of their areas.
Triangle
The odd one out is the cube which is a 3D shape whereas the rest are 2D shapes if that is your question.
Because they are cooresponding shapes
It is not possible. A quadrilateral, by definition has four sides. And the number four, by definition is not an odd number.
Circles, ellipses, and lots of other similar shapes. Any regular polygon with an odd number of sides.
triangle pentgon heptagon nonagon etc.
All regular polygons with an even number of sides. Irregular polygons with an odd number of sides can have parallel sides. There are also non polygonal shapes that can have parallel sides.
Have you seen the odd shapes they have to fit.
One set of 3-d shapes meeting the requirements of the question is all prisms with regular, odd-sided polygons as bases.
they can be circular, triangular, and other odd shapes.
