A three dimensional shape (triangle) in which all the sides and all the angles are different is called an "Scalene Triangle"
There are 3 types of triangles:
1. Equilateral triangle - all 3 sides equal
all 3 angles equal (i.e., 60 each)
2. Isosceles triangle - 2 sides equal
2 angles equal
3. Scalene triangle - no sides equal
no angles equal
A circle. One side, zero angles. Also a line as it is a 1-dimensional shape.
A heptagon.
A Pentagon
A scalene triangle is a shape that has no sides or angles with the same measurements.
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 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.
Squares and rectangles have a two-dimensional shape with four sides and four right angles.
uhh, a triangle?
A scalene triangle is a shape that has no sides or angles with the same measurements.
A 5 sided shape with 5 angles is a pentagon
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.
No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.
A square is a two-dimensional shape with four equal sides and four right angles.
