Answer:
a) line segment
b) point
c) line
Step-by-step explanation:
A line segment is made up of 2 points.
No matter where the lines intersect (doesn't have to be perpendicular), it forms a point.
A line is straight, hence the 3 collinear points.
Perimeter is the sum of all sides in the figure. Here, all six sides are equal in length so it would be:
p = 6 * side
p = 6 * 3.9
p = 23.4 cm
In short, Your Answer would be: 23.4 cm
Hope this helps!
