For 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

Why are two congruent triangles also similar?

What is SSS used for in geometry?
SSS is a postulate used in proving that two triangles are congruent. It is also known as the "Side-Side-Side" Triangle Congruence Postulate. It states that if all 3 sides of a triangle are congruent to another triangles 3 sides, then both triangles are congruent.
What are the uses of quadrilaterals in daily life?
From ancient times, properties of quadrilaterals have been used especially in art, design and architecture. Diagonal of a rectangle divides it into two congruent triangles and the idea of congruency especially in triangles had been used by Egyptians to build The Great Pyramids of Giza!!!!! The idea of congruency of triangles initially from diagonal of quadrilaterals also helped Leonardo Da Vinci to paint the world famous 'Monalisa'!!!!! So, what other wonders do you want from quadrilaterals????!!!????
What is the rule stating that if 3 sides of a triangle or congruent to another triangle they are congruent?
Rules for congruency of triangles 1. Sss- three sides are equal 2. Sas- when two sides and one angle are equal 3. Aas- two angles and one side are equal. Rules for similarity of triangles 1.aa - two anles equal hence third also 2. Sss - ratio of corresponding sides is equal.
What is postulate?
Postulate:- A statement that is accepted as true, that forms the basis of a theory, etc.It also has a synonym:- posit
Are equilateral triangles also scalene triangles?
No
Are right triangles also equilateral triangles?
Generally not
Is some right triangles are also equilaterial triangles?
No
All isosceles triangles are also equilateral triangles?
No. All equilateral triangles are isosceles, but not all isosceles triangles are equilateral.
What is also called an axiom?
In classical studies, it is also called a postulate.
Are some right triangles also the same as equilateral triangles?
No...
Are some scalene triangles also right triangles?
true
If all corresponding sides and angles of two triangles are congruent those triangles are?
The triangles are also congruent.
What are the two kinds of geometry?
euclidean Geometry where the parallel line postulate exists. and the is also eliptic geometry where the parallel line postulate does not exist.
Are all equilateral triangles also isoscelles triangles?
Yes. But not all isosceles triangles are equilateral.
What is three types of triangles?
They are: right angle, isosceles and equilateral triangles There are also scalene and obtuse triangles
Are all scalene triangles also acute triangles?
no you can have an obtuse scalene triangle
True or false All equilateral triangles are also isosceles triangles?
True
True or false all isosceles triangles are also equilateral triangles?
False.
What other discoveries helped Dalton formulate his postulate?
I am also without an answer
Rules that are accepted without proof Also called amioms?
its a postulate.
Are some right triangles are also equilateral triangles?
No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
Are some scalene triangles also isosceles triangles?
Scalene triangles those triangles in which all the sides are of different lengths, but in isosceles triangles two sides of the triangle are equal in length. Therefore, no scalene triangle can ever be isosceles.
Can you show me the equilateral that is also an acute triangles a pictue of it?
All equilateral triangles are acute triangles, since all the angles are less than 90 degrees.
Which figure will contain 33 total triangles if figure 1 has 3 triangles and figure 2 has 5 triangles?
The simplest pattern is 2n+1, so the 16th figure will have 33 triangles. Of course, if you are creating new triangles and also keeping the old triangles, this would be different.
