During takeoff and landing, Concorde flew at a steep angle, with its front end tilted ... streamlining the plane's shape and allowing it to efficiently pierce the air. It's a classic aerodynamic ...

subtract the sum of the given angles from the sum of the interior angles. A polygon is any closed plane or 2D shape with multiple straight sides. Circles are not polygons because they're curved ...

It may be necessary to use Pythagoras' theorem and trigonometry to solve a problem. The shape ABCDEFGH is a cuboid. Length AB is 6 cm, length BG is 3 cm and length FG ...

Following is a full transcript of the video. Wing shapes are designed to generate lift. This keeps the plane in the air. Ice and snow can build up on planes. Ice buildup can change the shape of ...

Sylvia Lavin, in Kissing Architecture Could we extend our focus to the most fundamental and omnipresent architectural surface—the ground plane? How does the treatment of the ground influence the ...
