Which statements are true about polygons? Select three options.

All sides and all angles in a polygon are congruent.
The sides of a polygon are segments that intersect exactly two other segments, one at each endpoint.
In a polygon, all segments with a common endpoint are collinear.
If all of the sides of a convex polygon are extended, none of them will contain any points that are inside the polygon.
The extension of at least one side or diagonal in a concave polygon will contain a point that is inside the polygon.

answer: options?

step-by-step explanation:

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

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.

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
