Answers:equilateral triangle has rotational symmetry of 3. (Rotate it 1/3 of a turn and it maps exactly onto itself). No triangle has rotational symmetry of 2. Any non-equilateral triangle has at least one unique angle (and side), so it has no rotational symmetry.
Answers:an object has rotational symmetry if after rotating it a given amount(not 360 degrees), it is identical to the starting position. Take a square, rotate it 90 degrees, and it is still a square with the same side positions. An equilateral triangle and 120 degrees is the same. A tiger's face cannot be rotated any less than 1 full rotation and still look the same as the original face(upside down does not count), and neither can a maple leaf. However, a circle can be rotated by any angle and still be symmetrical, so it has infinite rotational symmetry.
Answers:The three lines of symmetry in an equilateral triangles are the perpendicular bisectors ( they are the medians and the altitudes) and also the angle bisectors. The intersection point divides any altitude into a 2 to 1 ratio.
Answers:3. the line of symmetry would be the angle bisector of each of the 3 angles.
