What shapes don't have a right angles?
Shapes that do not have right angles include circles, ovals, and various types of polygons such as triangles (specifically acute and obtuse triangles), and irregular polygons. Additionally, shapes like ellipses and curves, such as parabolas, also lack right angles. These shapes can have angles of varying degrees, but none equal to 90 degrees.
What shapes do not have any right angles or angles?
Shapes that do not have any right angles or angles are typically referred to as "curvilinear" shapes. Examples include circles, ellipses, and ovals, where the boundary is smooth and continuously curved without any vertices or corners. These shapes are defined by their curves rather than angular measurements.
