Which statement describes the order of rotational symmetry for an isosceles triangle? an isosceles triangle has an order 0 rotational symmetry because there is no angle at which it can be rotated onto itself. an isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles. an isosceles triangle has an order 2 rotational symmetry because it has 1 pair of congruent angles. an isosceles triangle has an order 3 rotational symmetry because it has 3 angles.

B. An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.

Step-by-step explanation:

We know that an isosceles triangle is a triangle that has two sides of equal length.

Also it has two equal angles opposite to the equal sides. [By isosceles theorem: The angles opposite to the equal sides of a triangle are equal.]

Therefore, it may not have all congruent angles. [ All angles equal in equilateral triangle only.]

When we rotate the isosceles triangle up to 360°, only after a rotation of 360° it appears exactly same as the original i.e only one time .

Therefore, An isosceles triangle has an order 1 rotational symmetry because it does not have all congruent angles.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

yes
