Answer:
Please follow the instructions below:
Start by drawing a straight line segment using a ruler. This will serve as the base of the triangle.
Place the compass at one end of the baseline and adjust its width to a suitable length for the sides of the triangle.
Keeping the compass width consistent, draw an arc from the other end of the baseline, intersecting the baseline on both sides.
Without changing the width of the compass, place the compass on one of the points where the arc intersects the baseline.
Draw another arc from this point, intersecting the first arc at a new topic.
Finally, draw a straight line connecting the two points where the arcs intersect.
By following these steps, you can construct an equilateral triangle logo for poster C. Remember to leave your construction lines if required.
