I have a program that takes user input from a textbox. Based on those 3 numbers it will tell them whether it is a right triangle, equilateral triangle or not a triangle. I've written 3 properties (get/set) to take the lengths. Now I need two readonly (get only) properties s to determine whether something is right or equilateral. I'm really not sure how I would write the formula in vb. I understand a right triangle is a2 + b2 = c2 but i'm not sure how I could process a math formula inside a property. I guess I am also trying to learn how these two new properties would interact with the 3 already written? Here is what I have so far. I do not yet have anything for the right triangle. Does this make sense and anybody know how to easily calculate a right triangle. The formulas online haven't really made sense to me in order to write it out in vb.

Code:
Public Class Triangle

    'declare integers for 3 triangle sides
    Dim m_intSide1 As Integer
    Dim m_intSide2 As Integer
    Dim m_intSide3 As Integer

    'declare integers for triangle type
    Dim m_intRight As Integer
    Dim m_intEquilateral As Integer

    'Triangle constructor, sides supplied
    Public Sub New(ByVal side1Value As Integer, ByVal side2Value As Integer, _
        ByVal side3Value As Integer, ByVal RightTriangleValue As Integer, _
        ByVal EquilateralValue As Integer)

        m_intSide1 = side1Value
        m_intSide2 = side2Value
        m_intSide3 = side3Value
        m_intRight = RightTriangleValue
        m_intEquilateral = EquilateralValue

    End Sub 'New

        'set m_intside1 value
        Set(ByVal Value As Integer)
            'if side 1 value entered is valid
            If (Value > 0) Then
                m_intSide1 = Value
            Else
                m_intSide1 = 0  'set invalid input to 0
            End If
