Triangle def is congruent to d'ef' by the sss theorem. which single rigid transformation is required to map def onto d'ef'? dilation reflection rotation translation

the answer is rotation :/

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
