    Post angles

    All the sides of a triangle are segments. How could it have angles then?

    As they say an angle is formed by two rays having the same end point...

    Can the definition be like this "it is formed by two segments having the same end points.

    I don't see why not... as long as you add that 'the length of the segments is irrelevant'.

    Angles are formed by two rays and one end point.
    Since triangles have segments as its sided, why do they say that it has three angles

    The answer to the question should now be clear (especially since I have merged some posts from another thread).

    Thread closed.


    Edit: Re-opened for the time being.

    I think you will find this interesting.
    A standard theorem in axiomatic geometry is the following.
    The union of any two sides of a triangle is a subset of an angle.

    thanks

    please help me again

    When we say that it is just a subset of an angle, does it mean that it is just a part of angle?

    Since it is just a subset of an angle, do you think that I can't consider that as real angle?

    If it is a real angle, can I consider the sides of the triangle as the sides of its angles though they are just segments?

    Post the sides of a triangle

    Are the sides of the triangle considered the sides of its angles?

    sides of triangles are in units like mm, cm or even m.
    sides of triangles are in degrees
    there is no such a thing as "sides of angles"
