Question 16 • (OC27) GEO-1206310-S1-Degele-VOL7006P
Rotational symmetry counts how many times a shape matches itself during a full 360° turn. An isosceles triangle does not match itself at any turn smaller than 360°, so its rotational symmetry has order 1. Thus, the correct statement is that it has order 1; having two congruent angles does not give it order 2.
