Bao wants to prove that if parallelogram ABCDABCDA, B, C, D has a right angle, then its diagonals are congruent. Bao says: "I can prove this using the fact that opposite sides in a parallelogram are congruent, and by establishing the congruence of a single pair of triangles." Which pair of triangles is Bao referring to, and which criterion should he use for establishing congruence? Choose 1 Choose 1

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

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.
