Negative reciprocal slopes always represent perpendicular lines.
A circle through the Earth's sphere perpendicular to the observer's latitude
Lines of latitude and longitude are perpendicular because they represent different angles to the reference point of the Earth's center. Lines of latitude are parallel to the equator and represent distances north or south from it, while lines of longitude converge at the poles and represent distances east or west from the Prime Meridian. Their perpendicular relationship helps to pinpoint specific locations on the Earth's surface using a coordinate system.
dip is angle of ore body from horizontal plan.and strike is perpendicular to dip.these are important parameters to represent orientation of ore body.
Basis vectors in a transform represent the directions in which the coordinate system is defined. They are typically orthogonal (perpendicular) to each other and have unit length. These basis vectors serve as building blocks to represent any vector in the space.
Hachured contour lines on a topographic map indicate a depression or a hole in the ground. They are lines that have small perpendicular lines extending from them, pointing inward toward the depression or lower elevation area they represent.
It depends on the context. It can mean 1000 (as in kilo). It can represent a constant, specially a constant of proportionality. It can represent a unit vector in the third mutually perpendicular direction (the z-axis). It is often used as an index (often after i and j).
No . It is not perpendicular
yes it is perpendicular
No, a rhombus is not perpendicular.
