1. It has three angles that are unequal 2. Its has three unequal sides
looawawer The sides are of equal lengths and the internal angles are each 60 degrees.
It has 3 sides It has 3 interior angles that add up to 180 degrees It will tessellate leaving no gaps or overlaps
Some of its attributes are:* Three congruent sides * Three congruent angles * Each of these angles has a measure of 60° (since the sum of the angles must be 180°) * Three axes of symmetry * Looks the same when rotated 120°, or a multiple thereof * All equilateral triangles are similar to one another
