On a circle, the tangent is always perpendicular to the radius. We use this key piece of information when finding the equation of the tangent. We then use our knowledge of the equation of a circle, and the equation of straight lines (y = mx + c) to find the equation of the tangent. Equation Of A Ci

Like a magical border, the Arctic Circle stretches around the world along the 66th parallel, spanning very different countries and regions. The vast region inside the Arctic Circle is also a true treasury of raw materials. Author: ZDF/Terra X/Spiegel TV Media/R.Hillmann/R.Marel/C.Gerisch/A.Kindler/
Near Greenland, scientists used radar data to discover an 800-meter-deep gorge beneath an ice sheet, and near Alaska, salt water plunges to depths of up to 4,000 meters. The largest "waterfall" on earth. Author: ZDF/Terra X/Spiegel TV Media/R. Hillmann/R. Marel/C. Gerisch/A. Kindler/Maximilian Mohr
Let’s discover some more circle theorems so that we can solve all types of geometrical puzzles. We discovered these 4 theorems in part 1: Angle at the centre is double the angle at the circumference The angle in a semi-circle is 90 degrees Angles in the same segment are equal / Angles subtended by

Stonehenge is a name given to a mysterious prehistoric monument that stands tall on the Salisbury Plains amid the idyllic English countryside of Wiltshire. Over a million tourists flock to the enigmatic site each year, marveling at the ancient architecture. But, despite the popularity of one of the

A hurricane only develops when the sea is at least 26 degrees warm. Then the storms build up their destructive force. While it is almost windless in the eye of the hurricane, tropical storms with speeds of up to 300 km/h circle around it. Author: ZDF/Terra X/R. Marel/S. Hillmann/C. Gerisch/A. Kindl
