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.
The rectangle
square
No. The sides of a shape don't need to be equal in length to be parallel.
pentagon
a square
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.
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.
Isometric
A shape is considered regular when all sides are of equal length.
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
The rectangle
square
Not exactly. They are two names for the same shape. The typical shape consists of a four-sides figure with opposite sides (and angles) equal. Each pair of parallel sides are the same length.
