Triangle class

Defines a mathematical triangle strictly via 3 points in 2D space.

Implemented types

Constructors

Triangle({required Point<num> p1, required Point<num> p2, required Point<num> p3})
Creates a Triangle by defining its three vertices.

Properties

area → double
The total surface area of the shape.
no setteroverride
boundingBox → Rectangle
The smallest axis-aligned rectangle that completely encloses the shape.
no setteroverride
centroid → Point<double>
The mathematical center of mass of the shape.
no setteroverride
hashCode → int
The hash code for this object.
no setterinherited
p1 → Point<num>
The first vertex.
final
p2 → Point<num>
The second vertex.
final
p3 → Point<num>
The third vertex.
final
perimeter → double
The total length of the shape's boundary.
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sideA → double
The first side length.
no setter
sideB → double
The second side length.

Methods

noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
rotate(double angle, [Point<num>? origin]) → Triangle
Rotates the shape by the given angle (in radians) around the origin. If origin is omitted, rotates around the shape's centroid.
override
scale(num factor) → Triangle
Scales the shape uniformly by the given factor originating from centroid.
override
toString() → String
A string representation of this object.
override
translate(Point<num> offset) → Triangle
Translates the shape by the given vector offset.
override

Operators

operator ==(Object other) → bool
The equality operator.
