"What is a new definition of an isosceles triangle, based on the triangle's reflectional symmetry? Does the definition you came up with apply to the equilateral triangle as well? Explain."
I really need help with this question. I do not understand it at all. Is it talking about how an isosceles has two lines of reflectional symmetry while an equilateral triangle has three lines of reflectional symmetry?
I really don't understand..Please help me!

An isosceles triangle is a triangle with (at least) two equal sides...has one line of reflectional symmetry
An equilateral triangle is a triangle in which all 3 sides are the same size (the angles are all the same as well...60)...has 3 lines of reflectional symmetry

An isosceles triangle is symmetric about the line whose segment is its height (perpendicular to the base and passing through the apex point). I can't draw it, but it's simpler than it sounds.

~There is this person who is usually in the front of the classroom, generally older than the rest of the class who gets paid to answer questions just like this one. We call him or her a teacher. Ask him or her, that's what he's/she's there for. There is also this dumb thing they hand out at the beginning of the school year called a text book. Open it. Then read it. You'll be amazed what you can learn with a little effort, and YahooAnswers is not the place where you'll learn it.
