# Are two isosceles triangles always similar? Are two equilateral triangles always similar? Give reasons for your answers to both questions.

Isosceles triangles are not always similar, but equilateral triangles are always similar.

For two triangles to be similar the angles in one triangle must have the same values as the angles in the other triangle. The sides must be proportionate.

Two isosceles triangles are not always similar. Similarity of triangles depends on having proportional corresponding sides. Isosceles triangles have two sides of equal length, but the third side may vary in length. Therefore, if the third side of one isosceles triangle is different from the third side of another isosceles triangle, they will not be similar.

On the other hand, two equilateral triangles are always similar. This is because equilateral triangles have all three sides of equal length and all three angles equal to 60 degrees. Since all corresponding sides and angles are congruent, any two equilateral triangles will be similar.

Two isosceles triangles are not always similar because they may have different angles. However, two equilateral triangles are always similar because they have equal angles.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
