Question

Equilateral triangle can be constructed on any given _________.

• A. line segment
• B. point
• C. infinite ray
• D. arc

Answer 1

The correct option is A line segment

An equilateral triangle can be constructed on any given line segment.

So, if a line segment AB is given, we will cut two arcs taking the length of the line segment as radius and end points of line segment as the centers.

Join the end points of the line segment with the common point point of the arc to get the required equilateral triangle.
