Ricky draws a square. He claims that any rotation about the center of the square that is a multiple of 30 degrees will carry the square onto itself. Which statement best describes Ricky’s claim? A. Ricky’s claim is incorrect since not all rotations that carry a square onto itself are multiples of 30 degrees.
B. Ricky’s claim is incorrect since not all rotations that are multiples of 30 degrees carry a square onto itself.
C. Ricky’s claim is correct since any rotation that carries a square onto itself is a multiple of 30 degrees.
D Ricky’s claim is correct since any rotation that is a multiple of 30 degrees carries a square onto itself.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
