Yes.
Opposite and adjacent sides.
Two sides adjacent to a right angle.

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".
Any irregular polygon can have a pair of adjacent sides that do. Every pair of adjacent sides in every rectangle do.
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.
Right Angle! (:
The adjacent sides of a square are the two sides that meet at a vertex. In a square, each angle is a right angle (90 degrees), and all sides are of equal length. For example, if you consider one corner of the square, the two sides extending from that corner are its adjacent sides.
