SimilarPolygon: Creates a similar polygon to a given one

In LearnGeom: Learning Plane Geometry

Description

SimilarPolygon creates a sheared polygon from a given one

Usage

SimilarPolygon(Poly, k)

Arguments

Poly	Polygon object, previously created with function CreatePolygon or CreateRegularPolygon
k	Positive number that represents the expansion (k > 1) or contraction (k < 1) factor which is applied to the original polygon

Value

Returns a similar polygon, exapended or contracted, to the original polygon

Examples

x_min <- -5
x_max <- 5
y_min <- -5
y_max <- 5
CoordinatePlane(x_min, x_max, y_min, y_max)
P1 <- c(0,0)
P2 <- c(1,1)
P3 <- c(2,0) 
Poly <- CreatePolygon(P1, P2, P3)
Draw(Poly, "blue")
k <- 2
Poly_similar <- SimilarPolygon(Poly, k)
Draw(Translate(Poly_similar, c(-1,2)), "orange")
