A terrain park is an outdoor area that contains terrain that allows skiers and snowboarders to do tricks. Terrain parks have their roots in skateboard parks and many of the features are common to both. One of the first in-bounds terrain parks was the "Snowboard Park" built in 1990 at the Vail resort[1]. The park was copied soon in other resorts. Today most resorts have terrain parks, with many having multiple parks of varying difficulty. Some resorts are almost exclusively terrain parks such as Echo Mountain Park in Idaho Springs, Colorado, USA. In Colorado there has been a recent trend for defunct resorts such as Squaw Pass (now Echo Mountain Park) to be reopened, catering to terrain park users. Terrain parks (in the United States and Canada) have designations with respect to safety similar to standard alpine slopes. They differ in their designation and degrees of difficulty. They are identified with orange ovals to differentiate them from standard slopes, and are further distinguished by Large, Medium, o
360 degreesAny triangle inside angles total to 180 degrees.
Circles measure 360 degreesAny quadrilateral as well.Try to picture this, if you take a rectangle, and make a diagonal line across it, you have two triangles. Triangles will ALWAYS measure up to 180 degrees, so since you have two, 180X2=360
A parallelogram is a planar figure. It is a quadrilateral (four sided figure) with opposite sides parallel and of equal length.Squares and rectangles are special cases of a parallelogram. Further, the square is a special case of a rectangle.It is a 4 sided quadrilateral with 2 pairs of parallel sides and 2 equal interior obtuse and 2 equal interior angles that add up to 360 degreesany thing that has two sets of parellel lines
