Given a list of atomic model
a. electron shells outside a central nucleus.
b. hard, indivisible sphere.
c. mostly empty space which list of atomic model descriptions represents the order of historical development from the earliest to most recent?

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
