right triangle
a square
similar shapes have corresponding angles that are equal. Also, any length in one shape is equal to the scale factor times the corresponding length in the other shape.
A shape is considered regular when all sides are of equal length.

No. The sides of a shape don't need to be equal in length to be parallel.
pentagon

Isometric
A degenerate polygon is a shape with at least one side that is collapsed or has zero length, making it appear as a line or a point. This differs from a regular polygon, which has all sides of equal length and all angles of equal measure.
In geometry, it refers to two shapes that are identical in shape and size. If one shape can be moved - without stretching or cutting - so that it exactly covers another, then the two shapes are said to be congruent.

Any regular shaped polygon has equal angles and equal sides
Equilateral means "equal length". Polygon means "many sided shape". So an equilateral polygon is any many-sided shape where the sides are all equal in length, such as a rhombus
