What does 2D shape mean?
It means two dimensional such as the shape of a polygon or a rectangle that has dimensions of length and width.
What is the difference between perimeter and area of polygon?
perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)
Are 2 rectangles similar?
Only if they both have the same ratio of length to width. Since every square has the same ratio of length to width ( it's 1 ), all squares are similar. Gee, when you think about it, every regular polygon is similar to every other regular polygon with the same number of sides. I never realized that.
What is a 3 d shape?
A 3D shape stands for Three-Dimensional. The three dimensions are Height, Width and Depth. A line just has height, so it is 1D. A polygon has both Height and width so it's 2D. A three dimensional object has all three; Height, Width and Depth.________^Height/Length = 1D-------------------| || | Depth |/ |----------------- |
How do you determine the area and perimeter of geometric figures?
Area is length x width. Meanwhile Perimeter is the addition of all the lengths and widths of the entire geometric polygon.
