Tangent rays are the migratory sun rays that skim over the earth's surface at high latitude locations (Polar Regions). These rays also occur during dusk and dawn at any latitude.
Tangent rays will hit any part of the earth on any day at sunrise and at sunset.

The December solstice marks the official beginning of winter. The tangent rays of the sun hit the arctic circle.
Tangent.
The tangent ray refers to either the northernmost or southernmost hemisphere where the vertical rays refers to direct sun. During the June 21 solstice, the latitude rays in the southern hemisphere would be 66.5 deg S (Antarctic Circle)

During the winter solstice the Sun's rays are tangent to the Arctic and Antarctic Circles. At this time the North Pole is facing away from the Sun, while the South Pole is facing into the Sun.
Any latitude has tangent solar rays, at local sunrise and sunset. At the appropriate time of year, latitudes greater than 66.5° north or south can experience tangent solar rays at any point in a 24-hour day.
At the time of the equinoxes, the sun's rays would be nominally tangent to the Earth at the north and south poles. Those are 90 degrees north and south of the equator respectively. Also I think at either 23.5 degrees north or 23.5 degrees south at sunrise and sunset.
Secants are chords that go through a circle ONCE! Tangents are rays or segments with one point touching the border of a circle and nothing else.
A common tangent is a line which is tangent to two (or more) curves.
