2D shapes can be found printed in a book or you can draw them on a piece of paper. 2D shapes have sides and corners (also called vertices). Here are some 2D shapes you might know.

Year 2 For Year 2, the 2D shapes posters introduce shapes like equilateral triangles, squares and regular hexagons. Each poster clearly identifies the number of sides and vertices for each shape. This ...

Description Need to extract vertices from 2D grid-based shapes? Tired of manually counting grid cells? Let this tool handle it for you! First draw a valid shape (all cells but the first must be ...

It discusses calculations for perimeter and area in 2D shapes and expands to surface area and volume for 3D shapes. Visual diagrams and real-life examples demonstrate where each type of shape is ...

This paper presents an improved algorithm to achieve 2D image shape manipulation by real-time control. The shape is discretized as regular equilateral triangles mesh. User places handles on triangle ...
