Častá chyba:
Learners sometimes confuse "vertex" with "vortex" because they look similar. "Vertex" is a point or corner; "vortex" is a spinning mass of liquid or air. Learners may also use "corner" in formal math answers where "vertex" is expected.
Význam
corner point where lines meet
Kolokace
vertex of a triangle
|vertex of an angle
|vertex of a polygon
|adjacent vertex
|graph vertex
|vertex shader
Synonyma
corner (A more general, everyday word for the point where sides meet; not limited to mathematical contexts.)
|
node (Preferred in graph theory and networks for a connection point; less common for simple geometric shapes.)
Antonyma
center (Refers to the middle point of a shape, which contrasts with a vertex as a boundary or corner point.)

Definice
The point where two or more lines, edges, or rays come together, like a corner of a shape or a point in a network.
The point where two or more lines, edges, or rays meet, especially the corner of a geometric figure or a node in a graph or network.

csúcspont
B2
Vzorec užití:
the vertex of [a curve/parabola]
The parabola opens upward, so its vertex is a minimum point.
A parabola felfelé nyílik, ezért a csúcspontja minimumpont.
You can read the vertex directly from the quadratic in vertex form.
A csúcspont közvetlenül leolvasható a másodfokú függvény csúcsalakjából.

Completing the square helps you find the vertex of the quadratic function.
At the vertex of the curve, the slope is zero.
Učební příklady
The vertex of this parabola is at (2, −3).

Častá chyba:
Learners sometimes think the word "vertex" refers to the whole curve or graph instead of just one point. They may also forget that a parabola has only one vertex, not several.
Význam
highest or lowest point of a curve
Kolokace

|parabola's vertex
|find the vertex
|vertex form
|maximum vertex
|minimum vertex
Synonyma
turning point (Emphasizes the change in direction of the curve; less technical and not restricted to mathematics.)
Antonyma
midpoint (Refers to a central point between two ends, contrasting with a vertex as an extreme point of the curve.)
Témata

Definice
The single point on a curve, especially a parabola, where it is the highest or the lowest.
The point on a curve, especially a parabola, at which it reaches its maximum or minimum value.
