right angle
In geometry and trigonometry, a right angle is an angle that bisects the angle formed by two adjacent parts of a straight line
Got it
angle
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle
Got it
line segment
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints
Got it
points
In modern mathematics, a point refers usually to an element of some set called a space
Got it
line
The notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth
