There are three sides, hypotenuse, opposite and adjacent. But the adjacent and opposite are not fixed sides: it depends on which of the two acute angles you are examining.For either of the non-right angles, the adjacent side is the one which forms the angle, along with the hypotenuse. For the given angle θ, the length of the adjacent side compared to the hypotenuse (adjacent/hypotenuse) is the cosine (cos θ).

That would be a right angle: The measure of complementary angles adds up to 90 degrees. Adjacent angles are angles that share one common side and one common vertex, but no common interior points (the angles don't overlap). The non-common sides of two adjacent angles are the two "outside" sides (the unshared sides). Two adjacent and complementary angles would form a right angle split by a ray/line, and not necessarily bisected (perfectly divided in half).

It can have a right angle, or more than one right angle, but it also is possible that it does not have any right angles.

No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).

If the other angle is smaller than the right angle, it is an acute angle.If the other angle is the same as the right angle, it is a right angle.If the other angle is bigger than the right angle but smaller than two right angles, it is an obtuse angle.If the other angle is the same as two right angles, it is a straight angle.If the other angle is bigger than two right angle but smaller than four right angles, it is a reflex angle.After four right angles, the other angle starts back at being an acute angle.

In a right angle triangle the adjacent angle is at the base of the hypotenuse and next to the right angle

A right angle.

Right Angle! (:

If the noncommon sides of two adjacent angles form a right angle, then the angles are complementary angles.

the vertices if there are any if not it is not a angle. don't forget about the angles such as a right angles,acute angles,or obtuse angle

Yes. This is true because opposite angles are congruent and adjacent angles are supplementary.

Right angle, obtuse angle, acute angle, supplementary angle, complementary angle, interior angle, exterior angle, adjacent angle

Since a field is rectangular, it has 4 right angles, each of them measuring 90°

Adjacent angles will be right by each other and equal 180 degrees. Vertical angles will be opposite and equal to each other.
