A two-dimensional shape (polygon) is said to be "regular" (or equilateral) if all its sides are the same length and all its angles are the same angle. A regular pentagon, for example, has 72-degree angles on all five angles, and all its five sides are the same length.
A circle. One side, zero angles. Also a line as it is a 1-dimensional shape.
the difference between a two dimensional shape and and a solid is that a two dimensional shape is plane and a solid you can see the whole shape a the inside.
Octagonal An octagon has eight sides and eight angles, and is a two-dimensional shape. In an equilateral octagon, each side has a degree measure of 135.
A square is a two-dimensional shape with four equal sides and four right angles.
A polygon; specifically a tetragon. A two-dimensional shape with four equal sides and four right angles is a square. A two-dimensional shape with two sets of equal sides and four right angles is a rectangle. A two-dimensional shape with two sets of equal sides and two sets of equal angles is a parallelogram. A parallelogram where each opposite angel bisects the shape is a rhombus. A two-dimensional shape with one set of equal, parallel sides and two sets of equal angles is a trapezoid. A three-dimensional shape with four triangular faces is a tetrahedron.
a heptagon
They are said to be irregular shapes or polygons
Squares and rectangles have a two-dimensional shape with four sides and four right angles.
Assuming it is a two dimensional shape, 12 sides implies 12 angles (interior or exterior).
A two-dimensional shape (polygon) is said to be "regular" (or equilateral) if all its sides are the same length and all its angles are the same angle. A regular pentagon, for example, has 72-degree angles on all five angles, and all its five sides are the same length.
A 5 sided shape with 5 angles is a pentagon
It is an 8 sided polygon known as an octagon
No, they are two-dimensional.
The inside of a two-dimensional shape is called its interior.
A circle. One side, zero angles. Also a line as it is a 1-dimensional shape.
the difference between a two dimensional shape and and a solid is that a two dimensional shape is plane and a solid you can see the whole shape a the inside.
