Best Answer

No.

Examples:

- The right angled triangles {3, 4, 5} & {6, 8, 10} are similar;
- The right angled triangles {3, 4, 5} & {5, 12, 13} are just two right angled triangles.

All the corresponding sides in congruent triangles are equal All the corresponding angles in congruent triangles are equal

No. All corresponding sides and angles have to be congruent for the triangles to be congruent.

The triangles are also congruent.

You could prove two triangles are congruent by measuring each side of both triangles, and all three angles of each triangle. If the lengths of the sides are the same, and so are the angles, then the triangles are congruent... if not, then the triangles are not congruent. If the triangles have the exact same size and shape then they are congruent.

They are not - if you consider congruent triangles to be the same.

Some, but not all. Triangles with 2 congruent sides are called isoceles triangles. Triangles with 3 congruent sides are called equilateral triangles.

sssThere are five methods for proving the congruence of triangles. In SSS, you prove that all three sides of two triangles are congruent to each other. In SAS, if two sides of the triangles and the angle between them are congruent, then the triangles are congruent. In ASA, if two angles of the triangles and the side between them are congruent, then the triangles are congruent. In AAS, if two angles and one of the non-included sides of two triangles are congruent, then the triangles are congruent. In HL, which only applies to right triangles, if the hypotenuse and one leg of the two triangles are congruent, then the triangles are congruent.

They are not - if you consider congruent triangles to be the same.

Congruent triangles are the same because all three sides measure the same length.

That's not a postulate. It's a theorem. And you have stated it.

no. if one triangles sides are all 2 and one triangles sides are all 3 then they are not congruent

Are congruent triangles.

no because isosceles triangles only have two congruent sides and the other one is different
