Hemispheres.
Shapes that are identical in every respect including size are called congruent.
Triangles
Any shape with straight edges can have perpendicular edges.
A non geometric shape can be defined as shapes with irregular contours, and whose edges are not straight. On the other hand, geometric shapes are shapes with regular contours and straight edges such as squares, triangles, or circles. ~by Kate Wellsonberg
This is a pattern made up of identical shapes, they must fit together without any gaps and the shapes must not overlap. Multiple regular shapes are squares, triangles, hexagons and dodecagons
Shapes that are identical in every respect including size are called congruent.
Shapes with straight sides are called polygons
A quadrilateral.
They are called Polygons.If all the sides are straight lines, then a polygon.
When they are identical in sizes and angles
congruent
Congruent shapes are identical in size and angles
Regular polyhedra have identical faces.
Non-linear equations represent shapes other than straight lines.Non-linear equations represent shapes other than straight lines.Non-linear equations represent shapes other than straight lines.Non-linear equations represent shapes other than straight lines.
It's not that easy to answer because a straight angle is like a straight line and I think that it would be on either every or none of the shapes that I would know of. Any shape has a right, obtuse,or acute angle. So, I am guessing that no shapes have straight angles. or that a straight angle is in every angle which is not true.
There are infinitely many of them so it is not possible to list their names. If the sides are all straight lines, they are collectively called polygons.
