Question

Know the tangent line or point for the different types of map projections.

a) True
b) False

Answer 1

Tangent lines or points are used in map projections to preserve accurate scale and shape.

Step-by-step explanation:

In map projections, tangent lines or points are used to preserve accurate scale and shape.

Depending on the type of projection, the tangent line or point may be positioned at certain locations on the Earth's surface. For example, in the Mercator projection, the Equator is the tangent line.

In the Lambert conformal conic projection, two standard parallels serve as tangent lines. These tangent lines or points help maintain the accuracy of distances and angles on the projected map.
