A right angle is 90 degrees.
By "double right cone" do you mean one right cone sitting normal with another right cone upside-down atop the first cone? If so, then we you take that double right cone and intersect it with a plane at different angles, you get the conic sections. (i.e. hyperbola, parabola, elipse, circle)
to the right
The Sine function (abbreviated sin) takes an angle and gives a ratio which is based on the sides of a right triangle. If you have a right triangle, and one of the angles (not the right angle) is labeled y then sin y equals the length of the side opposite of angle y divided by the length of the hypotenuse. The hypotenuse of a right triangle is the longest side, and is always opposite of the right angle.

appendicitis, mesenteric adenitis
The iliac area of the abdomen is also referred to as the iliac fossa.
Colon sigmoideum
The ilium is a large bone in your pelvis, the 'crest' of your hip. The Iliac fossa is the smooth internal surface of the ilium. It's the place that might hurt if you get constipation!
peri umbilical and appendix has the same spinal segment T10
The pain of appendicitis is felt at the umbilicus. Appendix lies in right iliac fossa. So this is referred pain.
Upper left
The iliac fossa region is located in the pelvic bone area, specifically on the inside surface of the ilium bone, which is one of the three bones that make up the hip bone. It is a shallow, bowl-shaped depression that serves as an attachment site for muscles and ligaments.
IN case of intestinal obstruction occur know it through x ray by presence of gas shadow in right iliac fossa and multiply fluid level
At first the signs can be an all over abdominal pain (most common), loss of appetite, and sometimes nausea and/or vomiting. But as it becomes more and more inflamed the pain becomes more localized to the bottom right of your abdomen, in front of your right hip bone, as this is where the appendix is located.
The right iliac fossa, located in the lower right quadrant of the abdomen, contains several important organs. Primarily, it houses the appendix, which is a small pouch connected to the large intestine. Additionally, portions of the cecum and the terminal ileum of the small intestine are also found in this area. In some cases, the right ovary and fallopian tube in females may also be located here.
