Answer 1

Answer:

Step-by-step explanation:

1.parallel:n geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. ... Parallel planes are planes in the same three-dimensional space that never meet. Parallel lines are the subject of Euclid's parallel postulate.

2.Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it. In the figure above, the line AB is perpendicular to the line DF. If they met at some other angle we would say that AB meets DF 'obliquely'.

3.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. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.

4.The radius of a circle is the distance from the center of the circle to any point on its circumference. The easiest way to find the radius is by dividing the diameter in half.
