SOHCAHTOA, Pythagoras, sine rule and cosine rule and all things trigonometry actually have a lot of uses in “real life”. Such as working out distances to things, heights of buildings and mountains, navigation at sea. An important part of “useful” trigonometry are angles of elevation and depression.
The area of a triangle is ½ the base X perpendicular height. If we don’t have the perpendicular height, there is another formula we can use: 1/2absinC which we look at in this video. VISIT us at www.fuseschool.org, where all of our videos are carefully organised into topics and specific orders, an

In this video we are going to look at the angles in polygons… the sum of all interior angles and the size of one interior angle. In another video we will look at exterior angles. What Are Polygons: https://bit.ly/3wxTXpY VISIT us at www.fuseschool.org, where all of our videos are carefully organi
Not every triangle is a right-angle triangle, so we can't always use Pythagoras and SOHCAHTOA to find missing sides and missing angles. We instead use the sine rule or the cosine rule. They can both be used to find either missing sides or missing angles in any triangle (right angle or not). Click h
As hurricane season unfolds, a helpful set of eyes mounted on the International Space Station allows scientists to observe massive storms from a special angle. http://science.nasa.gov/ Visit http://www.nasa.gov/station for more from the ISS Click here to see more videos: https://alugha.com/NASA
Triangles are the building blocks of all other straight-edged shapes. They were used for hundreds of years to create accurate maps and GPS today still works using trigonometry. Even the pixels on phones and screens use trigonometry.We need to know these things so that we can work out exact length
