Yes.
Make one triangle using hree matches.
Underneath the two vertices at the base of this triangle, make another two triangles, using six more matches.
You will find that there is an inverted triangle in the middle - the fourth.

Why can't you use AAA to prove two triangles congruent?
You can't use AAA to prove two triangles congruent because triangles can have the same measures of all its angles but be bigger or smaller, AAA could probably be used to prove two triangles are similar not congruent.
What theorem is used to prove the AAS triangle congruence theorem?
Excuse me, but two triangles that have A-A-S of one equal respectively to A-A-S of the other are not necessarily congruent. I would love to see that proof!
What marks used on a figure to indicate congruent angles?
marks used on a figure to indicate congruent
What is pathagreon therom?
its the therom that states that a2+b2=c2 :). it is used for triangles. i dont know about other shapes. but is for triangles
Can a toothpick be used as a standard unit?
No, because not all toothpicks are the same size. However, one single toothpick could be used as long as you always used the same one.
Can 15 toothpicks be used form 3 congruent hexagons?
no no no i said no and i don't know haha get it know no haha

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.
How does sas theorem answer?
The SAS theorem is used to prove that two triangles are congruent. If the triangles have a side-angle-side that are congruent (it must be in that order), then the two triangles can be proved congruent. Using this theorem can in the future help prove corresponding parts are congruent among other things.
Why can't you use AAA to prove two triangles congruent?
You can't use AAA to prove two triangles congruent because triangles can have the same measures of all its angles but be bigger or smaller, AAA could probably be used to prove two triangles are similar not congruent.
Which arrangement cannot be used to prove two triangles congruent?
SSA
How are congruent triangles used in real life?
Mostly congruent triangles are used for construction of things like bridges and buildings because they are considered more stable and strong to use (i hope that helps i had to learn this for a project)
What theorem or postulate can be used to justify that the two triangles are congruent?
Pythagorean theorem
Why are congruent triangles used in building?
ya , so i actually wanted the answer myself but i think it is because congruent triangle will give it a balance and support
What needs to happen before you can use the reason CPCTC in a geometric proof?
Before using Corresponding Parts of a Congruent Triangle are Congruent theorem (CPCTC) in a geometric proof, you must first prove that there is a congruent triangles. This method can be used for proving polygons and geometrical triangles.
What CANNOT be used to prove triangles congruent ASA. SSS. SAS.?
All three of those CAN .
Which cannot be used as a reason in a proof?
AAA (angle angle angle) cannot be used as a reason in a proof when proving triangles congruent .
