You can put this solution on YOUR website! Hello! I'll try to summarize some things here for you.
.
As we you know, all triangles have 3 sides forming 3 angles.
The sum of all angles must always add up to 180 degrees.
In the case of isosceles triangles, 2 of its sides and 2 of its angles must equal to each other. It does not matter their measurement, as long as both are the same.
There is one kind of isosceles triangle that we call a "right isosceles triangle". This triangle has one angle of 90 degrees and the other 2 are exactly 45 degrees each.

I hope this helps you. Otherwise, please keep posting questions.
