1.if a triangle is isosceles, then do its base angles HAVE to be congruent?

No....we just require that any two angles be equal

2.If a triangle has two congruent sides, does it have to be isosceles?

By the usual definition, if two sides are equal, the triangle is isosceles

3.If two angles of a triangle are congruent, does the triangle have to be isosceles'?

Yes....equal angles in a triangle mean that the sides opposite those angles are equal

4.Does an equilateral triangle have to be equilangular?

Yes.......equilateral triangles are always equiangular

5.Is the side opposite to the largest angle in a triangle the longest side?

Yep....the greatest angle is always opposite the greatest side
