 NOUN shape straight line a line traced by a point traveling in a constant direction
Meaning Example A line traced by a point traveling in a constant direction; a line of zero curvature. "the shortest distance between two points is a straight line" asymptote A straight line that is the limiting value of a curve chord A straight line connecting two points on a curve diagonal, bias A line or cut across a fabric that is not at right angles to a side of the fabric diagonal (geometry) a straight line connecting any two vertices of a polygon that are not adjacent diameter A straight line connecting the center of a circle with two points on its perimeter (or the center of a sphere with two points on its surface) element A straight line that generates a cylinder or cone perpendicular A straight line at right angles to another line radius A straight line from the center to the perimeter of a circle (or from the center to the surface of a sphere) secant A straight line that intersects a curve at two or more points tangent A straight line or plane that touches a curve or curved surface at a point but does not intersect it at that point vector A straight line segment whose length is magnitude and whose orientation in space is direction line A length (straight or curved) without breadth or thickness curve, curved shape The trace of a point whose direction of motion changes recta recta
