ReflectedPolygon: Creates the reflection about a line of a given polygon

In LearnGeom: Learning Plane Geometry

Description

ReflectedPolygon creates the reflection about a line of a given polygon

Usage

ReflectedPolygon(Poly, Line)

Arguments

Poly	Polygon object, previously created with function CreatePolygon or CreateRegularPolygon
Line	Line object previously created with CreateLinePoints or CreateLineAngle, to be used as the axis of symmetry

Value

Returns the reflection of a polygon about a line

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")
P1 <- c(-3,2)
P2 <- c(1,-4)
Line <- CreateLinePoints(P1, P2)
Draw(Line, "black")
Poly_reflected <- ReflectedPolygon(Poly, Line)
Draw(Poly_reflected, "orange")
