Here's ur answer 》》》





☆☆120 degrees is the answer as one rotation of an equilateral triangle becomes 60 degrees so 2nd rotation of an equilateral triangle will become 120 degree.☆☆



Hope it helps ☺⚡✌

Answer 2

The angle of rotation of an equilateral triangle is $120$°.

Explanation:

• Angle of rotation of a figure is the angle by which the figure should be rotated about a center of rotation such that it retains its original outlines.
• The number of times for the figure to retain its original outlines during a full $360$° rotation is called the order of rotational symmetry.
• For an equilateral triangle the center of rotation is the point of intersection of its medians.
• The angle of rotation for the above condition to stand true for an equilateral triangle is $120$°.
