Generic Interfaces

I am having trouble implementing a method in my class that I derived from my Generic interface using T data type. IComparableType

using System;
using System.IO;

namespace Modeul_11
{
    public interface IComparableType<T>
    {
        public int CompareTo(T other);
    }

}

using System;
using System.IO;

namespace Modeul_11
{
    public interface IComparableType<T>
    {
        public int CompareTo(T other);
    }

}

Shape

using Modeul_11;
using System;
using System.IO;

namespace Module_11
{

    //Abstract class that extends the interface
    public abstract class Shape : IComparableType<Shape>
    {
        public abstract double Area();

        public abstract string WhatAmI();

        public int CompareTo(Shape other)
        {
            //if shape1 is less than shape 2, return -1
            // if shape 1 is greater than shape 2, return 1
            //if shape 1 and shape 2 are equal, return 0
            return 1; //FIXME
        }


    }
}

using Modeul_11;
using System;
using System.IO;

namespace Module_11
{

    //Abstract class that extends the interface
    public abstract class Shape : IComparableType<Shape>
    {
        public abstract double Area();

        public abstract string WhatAmI();

        public int CompareTo(Shape other)
        {
            //if shape1 is less than shape 2, return -1
            // if shape 1 is greater than shape 2, return 1
            //if shape 1 and shape 2 are equal, return 0
            return 1; //FIXME
        }


    }
}

NOTE: IK IT LOOKS WEIRD BUT MY PROF CODES THIS WAY, SO DON'T WORRY ABOUT HOW FUNKY SOME THINGS LOOK. HE'S OLD SCHOOL my issue is where the commented "if statements" are in my shape class the example he gave was " if x.CompareTo(y) < 0, return -1" I am unsure how to do that here since there's no data fields
