is a unit for measuring angles. A full circle contains 360 degrees.
in geometry is a one-dimensional object that extends infinitely in both directions. It has no width or thickness, only length.
is a curved line that is part of a circle or other curved shape.
is a basic geometric shape with three sides and three angles.
is a whole number greater than 1 that has only two divisors: 1 and itself.
two lines or surfaces that are always the same distance apart and never intersect, no matter how far they extend.
is a part of a line that has a definite beginning and end. It's like a piece of a straight line with two specific points marking its boundaries.

Down

means forming a right angle (90 degrees) with another line or surface.
is an angle whose size has been determined using a tool like a protractor.
is a geometric figure formed by two rays (or line segments) that share a common endpoint called the vertex.
is used to denote the second derivative of a function.
is an angle formed on the surface of a sphere.
is a special type of angle that measures exactly 90 degrees.
in geometry is like a half-line that starts at a specific point and extends infinitely in one direction. It's like a beam of light shining from a source.
