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.
Uses of basic proportionality theorem?
The basic proportionality theorem is an important tool for proving similarity tests such as SAS. It is used in comparison of similar triangles and finding their measurements.
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!
Can 9 toothpicks s be used to form 4 congruent triangles?
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.
What marks used on a figure to indicate congruent angles?
marks used on a figure to indicate congruent
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.
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 .
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.

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 CANNOT be used to prove triangles congruent ASA. SSS. SAS.?
All three of those CAN .
What does sas mean in geometery?
It is an acronym for the postulate "Side Angle Side". This is used to determine a triangle's congruency to other triangles. SAS is grouped often with SSS, AAS, and ASA (all "A"s are angle, all "S"s are side.)
