• How do you use the distance formula and slope formula to prove properties of polygons?
patriot [66]

Answer:

distance formula= \sqrt{x} (x_{2} -x_{1} )^{2} + (y_{2} -y_{1} )^{2} = find the length(units) using coordinates.

slope formula= m=\frac{rise}{run} =\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }= determines slope of a line using two points on the line(coordinates)

When working with polygons the main properties which are important are:

The number of sides of the shape.

The angles between the sides of the shape.

The length of the sides of the shape.

length , width

straight lines , angles, vertices, vertex

A polygon is any 2-dimensional shape formed with straight lines.

a plane figure with at least three straight sides and angles, and typically five or more.

Step-by-step explanation:

<h2><u>answer= use distance and slope to determine that opposite side of a polygon are the same length and same slope</u></h2>
