Need help ASAP! ΔABC was dilated from the origin by a scale factor of 2 to create ΔA′B′C′. Which statement explains why the triangles are similar? Dilations preserve side length; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve betweenness of points; therefore, the corresponding sides of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve orientation; therefore, the corresponding angles of ΔABC and ΔA′B′C′ are congruent.
Dilations preserve angle measure; therefore the corresponding angles of ΔABC and ΔA′B′C′ are congruent.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
