Triangl
Triangl :
(Geom) A geometric three-sided, plane figure, the sides of which meet by pairs at three points called vertexes. The sum of the three interior angles is 180 degrees. Note: A triangle is called equila teral if all sides are equal, isosceles if two sides are equal, and scalene if no two sides are equal. Triangles are called acute if the largest angle is less than 90 degrees, right if one angle is 90 degrees, and obtuse if one angle is greater than 90 degrees. Trigonometry is the study of the relations between the angles and sides of a triangle
