GEOMETRY HELP WILL MARK BRAINLIEST

Step-by-step explanation:

The most common example of geometry in everyday life is technology. Be it robotics or computers or video games, geometry is applied to almost all the underlying concepts. The computer programmers are able to work because the concepts of geometry are always at their disposal.

GEOMETRY is the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogues.

Step-by-step explanation:

Flat shapes  like squares, circles, and triangles are a part of flat geometry and are called 2D shapes. These shapes have only 2 dimensions , the length and the width.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
