Assuming that a space figure means a 3-dimensional object, the answer is a square based pyramid.
A geometric figure is a figure of any shape and size, and can also be flat/plane ( meaning, two dimensional like triangle, equilateral., pentagon...) or solid (3 dimensional figure like cube, pyramid, sphere..).A geometric model is a geometric figure that represents real life object like butterfly, flower, earth, etc.So a geometric kite is a two dimensional geometric figure or model.
