Rhomboids, like triangles, may take various different shapes, but they always look like a lopsided diamond or rectangle. As both a noun and an adjective, rhomboid can be applied to anything with those shapes, such as certain muscles of the upper back when viewed from behind.
What shape is the rhomboid muscle?
Muscles connecting the upper extremity to the vertebral column. The rhomboid muscles (/ˈrɒmbɔɪd/), often simply called the rhomboids, are rhombus-shaped muscles associated with the scapula.
What does a rhombus shape looks like?
A Rhombus is a flat shape with 4 equal straight sides. Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram). And the diagonals “p” and “q” of a rhombus bisect each other at right angles.

The rhomboid major and minor are a group of deep intrinsic shoulder muscles that together with the sternocleidomastoid, trapezius, pectoralis muscles, latissimus dorsi, and serratus anterior, form the shoulder girdle.
Where are your rhomboids located?The Rhomboids are two muscles – Rhomboid Major & Rhomboid Minor. The two rhomboids lie deep to trapezius to form parallel bands that pass inferolaterally from the vertebrae to the medial border of the scapula.

A trapezoid is a four-sided flat shape with one pair of opposite parallel sides. It looks like a triangle that had its top sliced off parallel to the bottom. Usually, the trapezoid will be sitting with the longest side down, and you will have two sloping sides for the edges.
What is a Nonagon shape?
A nine sided shape is a polygon called a nonagon. It has nine straight sides that meet at nine corners. The word nonagon comes from the Latin word “nona”, meaning nine, and “gon”, meaning sides. So it literally means “nine sided shape”.

Is Diamond a shape?
Diamonds are unique shapes because they have many different geometric attributes. A diamond is a quadrilateral, a 2-dimensional flat figure that has four closed, straight sides. But a diamond is also categorized as rhombus, because it has four equal sides and its opposite angles are equal.
How long does a rhomboid strain take to heal?
