fictional maps that don't exsist
Straight lines.
Straight ones... Not truly lines, but segments
There is no kind of shape that has a straight line or curved line a kind of element of the following question is "space"...hope this helps
A quadrilateral has 4 straight lines joined together by their 4 vertices.
A topographic map typically has curved contour lines to represent elevation changes in the landscape. These lines connect points of equal elevation, allowing readers to visualize the shape and steepness of the terrain.
On a Mercator projection, meridians appear as straight, parallel lines running from top to bottom of the map, spaced evenly apart. This is because the Mercator projection is a cylindrical map projection that preserves straight lines of constant bearing, resulting in meridians being stretched vertically towards the poles.
Boundary lines on a map are often straight due to human-made demarcations such as survey lines, political agreements, or treaties. Straight lines can simplify border management and administration, reducing potential disputes over ambiguous boundaries. However, natural features like rivers and mountains can also create straight boundaries on maps.
It's kind of obvious seeing as 'oct' means eight... Anyway, there are eight straight lines in an octagon.
Contour lines or also known as isohypses, connect points of equal elevation on a map. Contour lines can be curved, straight or a mixture of both. The lines on a map describe the intersection of a real or hypothetical surface with one or more horizontal planes.
straight angle
By vertical lines, like meridians, but not always straight.
1. True direction (loxodromes are straight lines) 2. Local shapes
