In a study of heart rate in ocean-diving birds, researchers harnessed 10 randomly sampled, wild-caught cormorants to a laboratory contraption that monitored vital signs. Each cormorant was subjected to six artificial "dives" over the following week (one diver per day). A dive consisted of rapidly immersing the head of the bird in water by tipping the harness. In this way, a sample of 60 measurements of heart rate in diving birds was obtained. Do these 60 measurements represent a random sample? Why or why not?

ΔDCE ≅ ΔD'C'E'                            Option b.

Step-by-step explanation:

Here two triangles are given

When we move down  it creates the same shape triangle, therefore it has the same order of which the triangle is named.

Triangle is a shape has three angles so when we translated it down It will become as,

CD ≅ C'D'

CE ≅ C'E'

DE ≅ D'E'

SO, It will make three different kinds of triangles, That is why It is named as triangle.

Correct answer is:

ΔDCE ≅ ΔD'C'E'

Option B is correct.
