A tangent at that point where a straight line just touches a curve and a secant line when the straight line bisects the curve.
A straight or curved line truncated at one point.
A tangent
It is a point where one line (straight or curved) meets another line or a non-coplanar surface.
Input straight line joining mid -point of any two sides of triangle is parallel to the 3rd side and equal to half of it.
It is the midpoint of the straight line joining E and A.

No. Convex simply means that if you have a straight line segment joining any two points in (or on) a convex shape, then every point on that line segment in inside or on the shape. A convex shape can have 2 or more dimensions, it can by a polygon or have curved sides.
Input straight line joining mid -point of any two sides of triangle is parallel to the 3rd side and equal to half of it.
Most likely sinusoid.
The immediate surroundings of any point on a curved path can be considered as part of a circle: the circle of curvature at that point. Then the tangent to the path at that point is a line that meets the path at only one point in that neighbourhood and which is perpendicular to the line joining the point to the centre of the circle or curvature. The concept can be extended to straight segments of the path by assuming that the centre of curvature is at an infinite distance. In that case, the path and its tangent are the same line.
It is the midpoint of the straight line joining E and A.
A chord and the diameter is the largest chord of a circle. A2. Remember, the circle is the bit inside the curved line, NOT the curved line. [A circle is bounded by ... .] From any two points on a circle, you could erect a variety of lines, of which the shortest for any given quest would be a straight line. The other natural line joining two points would be the arc joining two points on the perimeter of a circle. * * * * * Actually, I believe that a circle IS the curved line. A circle is defined as the locus of all points that are at a constant distance from a fixed point (the centre). This is the boundary of the circle, not its interior.
Given a straight line joining the points A and B, the perpendicular bisector is a straight line that passes through the mid-point of AB and is perpendicular to AB.
A face, of a solid object, is a flat surface. If it is curved it is called a curved surface though sometimes it is also referred to as a face. Two faces meet at an edge, which is a line which may be straight or curved. Three or more faces meet at a point which is a vertex.
The slope of a curved line at a point is the slope of the tangent to the curve at that point. If you know the equation of the curve and the curve is well behaved, you can find the derivative of the equation of the curve. The value of the derivative, at the point in question, is the slope of the curved line at that point.
