Draw an equilateral triangle whose sides are 5.2 cm each.

Step 1:

Draw a line segment AB of length 5.2 cm.

Step2:

From Euclid’s third postulate, we know that we can draw a circle with any center and any radius.

Draw a circle with center A and radius AB.

Step 3:

Draw another circle with center B and radius BA.

Step 4:

The two circles meet at C. Join C to A and B to form ΔABC.

Thus, the required equilateral triangle is constructed.
