Octagon
That is the correct spelling of "oval" (an ellipsoid shape).
That is the correct spelling of "form" (shape or appearance, or a document).
The spelling "forge" is correct (to heat and shape metal, or the place it is done).
Words are spelled the same in cursive as in typing. Only the shape of the letters is different.
cuadrado
That is correct.
Shape.
The geometric quadrilateral shape (a parallelogram of diamond shape) is spelled "rhombus".
Octagon
Those letters spell an octahedron.
That is the correct spelling of "oval" (an ellipsoid shape).
The correct spelling is "circle" (a round shape).
Yes.You spelled it wrong also.To spell it correctly,spell it like this.pentagon
Octogon? If so, it's an 8 sided shape. The prefix "octo-" means 8.
The correct spelling is "quadrilateral" (a 4-sided shape).
The correct spelling is oval (an ellipse or egg shape).
