csúcs
B1
Usage pattern:
the vertex of [something]
Label each vertex of the triangle with a different letter.

Learner examples
This square has four vertices.

Draw a dot at each vertex of the polygon.
Rajzolj egy pontot a sokszög minden csúcsára.
The two lines meet at one vertex.
We added a new vertex to the network diagram.
The teacher showed us how to name each vertex with a letter.
Common mistake:
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.
Meaning
corner point where lines meet
Collocations
vertex of a triangle
|vertex of an angle
|vertex of a polygon
|adjacent vertex
|graph vertex
|vertex shader
Synonyms
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.)
Antonyms
center (Refers to the middle point of a shape, which contrasts with a vertex as a boundary or corner point.)

Definition
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
Usage pattern:
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.
Graph the function and mark the vertex clearly on the grid.
Completing the square helps you find the vertex of the quadratic function.
At the vertex of the curve, the slope is zero.
Learner examples
The vertex of this parabola is at (2, −3).
Ennek a parabolának a csúcspontja a (2; −3) pontban van.
We use the formula to find the vertex of the graph.
A képletet a grafikon csúcspontjának meghatározására használjuk.
Draw the vertex first, then draw the rest of the curve.
This quadratic has its vertex above the x-axis.
The teacher asked us to label the vertex on the picture.
Common mistake:
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.
Meaning
highest or lowest point of a curve
Collocations
vertex of a parabola
|parabola's vertex
|find the vertex
|vertex form
|maximum vertex
|minimum vertex
Synonyms
turning point (Emphasizes the change in direction of the curve; less technical and not restricted to mathematics.)
Antonyms
midpoint (Refers to a central point between two ends, contrasting with a vertex as an extreme point of the curve.)
Themes
mathematics
|geometry
|education
|science
Definition
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.

fejtető

Usage pattern:
the vertex of [the head/the skull]

Az orvos finoman megnyomta a csecsemő fejtetőjét.
Hair loss was most noticeable at the vertex of his scalp.
A hajritkulás a fejtetőjén volt a legszembetűnőbb.
In a normal delivery, the baby’s vertex usually appears first.
The incision was made just lateral to the vertex of the head.
Ultrasound confirmed a vertex presentation of the fetus.
Learner examples
The nurse touched the baby’s vertex very carefully.
A nővér nagyon óvatosan megérintette a baba fejtetőjét.
He is starting to go bald at the vertex.
Kezd kopaszodni a fejtetőn.
The vertex is the highest point of your head.
The doctor checked the soft area near the vertex.
In this drawing, the arrow points to the vertex of the skull.
Common mistake:
Learners sometimes confuse "vertex" with "vortex" or assume it always means a geometric corner. In medical texts, "vertex" refers specifically to the top of the head.
Meaning
highest point of the skull
Collocations
skull vertex
|palpate the vertex
|vertex presentation
|bald at the vertex
|shaved at the vertex
Synonyms
crown (A more common everyday word for the top of the head; less precise than the anatomical term "vertex".)
Antonyms
base of the skull (Refers to the lower back part of the skull, conceptually opposite to its highest point.)
Themes
medicine
|anatomy
|health
|body
Definition
The very top point of a person’s head or skull.
The highest point on the top of the human skull or head, used especially in anatomy and medicine.

Common mistake:
Learners may confuse this technical use with the more common geometric meaning, not realizing that here it refers to the highest point of a physical path in space.
Meaning
highest point of a trajectory
Collocations
vertex of its trajectory
|vertex of its orbit
|at the vertex of the path
|projectile vertex height
Synonyms
apex (General word for the highest point; not limited to trajectories but often used similarly in technical writing.)
Antonyms

Definition
The top point on the path of something that moves, like a rocket or a planet, when you watch it from one place.
