2triangles have identical side lengths and angle measures. the second triangle is rotated slightly to the left. which statement about the transformation is true? it is rigid because all side lengths and angles are congruent. it is rigid because no side lengths or angles are congruent. it is nonrigid because all side lengths are congruent. it is nonrigid because no side lengths or angles are congruent.

It is rigid because all side lengths and angles are congruent.

Step-by-step explanation:

2 triangles have identical side lengths and angle measures. The second triangle is rotated slightly to the left. It is a rigid motion.

Definition of rigid motion : -

The performance of any combination of the following actions, namely - translation, rotation or/ and reflection keeping the size and shape of a geometric body constant  is called performing 'Rigid motion'.

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
