Opposite and adjacent sides.
Two sides adjacent to a right angle.
legs
Mutually perpendicular, adjacent sides.Mutually perpendicular, adjacent sides.Mutually perpendicular, adjacent sides.Mutually perpendicular, adjacent sides.
That's the cosine of the angle to which the 'adjacent' side is adjacent.
A right angle.
They are: opposite, adjacent and hypotenuse sides for a right angle triangle
Those are the triangle's "legs".
Adjacent means next to. So you're asking what sides of a triangle are next to the right angle of a triangle. That would be the 2 shorter sides of the triangle or 'legs' of the triangle. The hypotenuse (which is the longest side of the triangle) is directly across from the right angle.
Any irregular polygon can have a pair of adjacent sides that do. Every pair of adjacent sides in every rectangle do.
Right Angle! (:
Sometimes as in a square, rectangle or a right angle triangle
