Qouadrilateral a has side length 6,9,9 and 12 quadrilateral b is a scaled copy of quadrilateral a, with its, shortest side of length 2. what is the perimeter of quadrilateral b? draw a picture to you

The perimeter of quadrilateral B is 12.

Explanation

Quadrilateral A has side lengths as  6, 9, 9 and 12.  In quadrilateral B, length of the shortest side is 2.

As quadrilateral B is a scaled copy of quadrilateral A, so the scale factor will be...

(Shortest side of B / Shortest side of A)

Now the remaining side lengths for quadrilateral B will be.....

and

⇒  3 , 3 and 4  

Thus, the perimeter of quadrilateral B is

-2/

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
