An isosceles triangle has two equal sides and two equal angles
Reflexive Postulate.
A triangle with no equal sides and no equal angles is called a scalene triangle. In contrast, a triangle with equal sides and equal angles is called an equilateral triangle. A triangle with two equal sides and two equal angles is an isosceles triangle.
A triangle with 3 equal sides is an equilateral triangle. A triangle with 2 equal sides is an isosceles triangle. There is no such thing as a triangle with ONE equal side. Equal to what? If you wish to stretch it and say each side is (equal to itself only ) not equal to any others it is a scalene triangle.
A triangle with no equal sides is a scalene triangle.
there isn't a AAA postulate because,,, for a triangle to be equal, there HAS to be a side in it
An isosceles triangle has two equal sides and two equal angles
There is no AAA theorem since it is not true. SSS is, in fact a theorem, not a postulate. It states that if the three sides of one triangle are equal in magnitude to the corresponding three sides of another triangle, then the two triangles are congruent.

Only if it is in the shape of a square

Someone correct me if I am wrong, but I don't believe triangles can be "equal", only congruent. The measurements can be equal, but not the triangle itself.The triangle congruency postulates and theorems are:Side/Side/Side Postulate - If all three sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Side/Angle Postulate - If two angles and a side included within those angles of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Side/Angle/Side Postulate - If two sides and an angle included within those sides of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Angle/Angle/Side Theorem - If two angles and an unincluded side of a triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.Hypotenuse/Leg Theorem - (right triangles only) If the hypotenuse and a leg of a right triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
YesFor two triangles to be congruent, their corresponding sides must be of equal length. But for triangles to be similar, they must only have equal angles. For there to be a SAS postulate for similarity, the two corresponding sides would have to be proportionate, not equal. If they were equal, the triangles would be congruent.So, an SAS postulate for similar triangles would mean that two of the sides of the smaller triangle are, for example, half the two corresponding sides of the other triangle. If also the corresponding included angles are equal, then the two triangles would be similar triangles.APEX: similar
The Side-Side-Side (SSS) postulate states that if all three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent. In other words, if the lengths of the three sides of one triangle are equal to the lengths of the corresponding three sides of another triangle, then the two triangles are congruent.
Both state that the whole is equal to the sum of the component parts.
