Radial and ulnar styloids.
The radius and the tangent are perpendicular at the point on the circle where they meet.
Either every point on the radius, or the centre of the circle.
Two points can meet only if they coincide. Since points are dimensionless, the area is zero.
The radius is DE
To determine the radius of a corner, measure the distance from the corner to the point where two straight edges meet. This distance is the radius of the corner.
The place where two points meet is known as an intersection in math.
Never. They are points on the same line. *------*
It's a polygon with 14 points (If the two ends meet) or 16 points (If the two ends don't meet).
Lines intersect if the meet at one point. Perpendicular lines also meet at one point, but their intersection is a right angle. Intersecting lines in the plane do not meet at two points.
Intersection or coordinates
Those bones meet at the elbow joint.
These are the points where three faces meet.
