How can I recognize the differences between congruence transformations in triangles(Math question)

[From: ] [author: ] [Date: 11-12-17] [Hit: ]
Please help me.and Im not talking about rotation and reflection only, theres 2 more.Ill definitely choose best answer if someone help me.-Do they give you any measurements for angles or for sides? If the measurement of the angles and sides have a matching counterpart,......
In math, how can i tell if a triangle is the reflection of another triangle? or rotation?
is there any rule i can use for that?
or should i stick with the look of the triangles?
Please help me.

Do they give you any measurements for angles or for sides? If the measurement of the angles and sides have a matching counterpart, it may be a reflection or a rotation. If the angles and sides do not have a matching counterpart, it cannot be a reflection or a rotation.

This next part takes a little imagination. Is it possible to "cut out" the triangle, keep it still face up, and lie it on top of the other triangle, and have them match up exactly? If you can do this by moving it around, but not flipping it over, you have a rotation. If you have to flip it over to make it work, you have a reflection.

Hope that helps!
