Does side-angle-side guarantee congruency between two triangles?

Yes, providing the angle is the one included between those two sides.
The conditions for congruency are:
SAS (2 sides and the included angle)
AAS (2 angles and a corresponding side)
RHS (right angle hypotenuse and another side)
SSS (3 sides).

What are three ways that triangles are congruent?
Triangles are congruent when:All three sides are the same length (SSS congruency)Two sides and the angle between them are the same length (SAS congruency)Two angles and the side between them are the same length (ASA congruency)
SSA does not guarantee congruence between two triangles?
True. Only if the given angle is between the two sides will the two triangles guarantee to be congruent (SAS), unless the given angle is a right angle (90°) in which case you now have RHS (Right-angle, Hypotenuse, Side) which does guarantee congruence.
When do you say that two triangles have the same shape?
well, they could be congruent, there are some rules for congruency, to be congruent two triangles have, ASA-two angles the same with a side length between them. SAS-two side lengths the same and a same angle between them. SSS-all 3 side lengths the same. RHS-if the triangles are right angles ,and the hypotenuse are the same. ;or they could be mathmatically similar. :)
The harmony between verbal and nonverbal communication is called congruency?
Yes.
Why can't ssa prove triangles congruent?
because neither side congruency nor angle congruency can be proved... to put it simply, this is because there would be too many variables with too little information if you set it up in an equation OR the fact that nothing is sandwiched between 2 parts like a side is not put between a side and an angle or vice versa, etc. In geometry class, we call this the "donkey theorem" (hence the acronym Angle Side Side)
Three congruent triangle?
Congruency can only be determined between two regular polygons.
AAA angle angle angle guarantees congruence between two triangles?
true apex :)
Is it true that AAA angle-angle-angle does not guarantee congruence between two triangles?
The answer is no. When two triangles are congruent all three corresponding sides are the same and all three corresponding angles are the same. Two triangles with the same corresponding angles can have corresponding sides different so they are not congruent.
If any two sides and any angle are congruent in two triangles then the triangles must be congruent.?
No. The angles must be an included angle, between the sides to guarantee congruence. For an example. imagine a triangle with two equal sides and a 60 degree angle between them and another triangle with the same two equal sides and a 120 degree angle between them.
What are SSS SAS RHS and AAS as regards proof of congruence?
These are all congruency tests for triangles. S=side A=angle R=right angle H=hypotenuse Take one of the tests for example. AAS If two angles and one side is the same between two triangles, then the triangles are congruent. A link is provided to the Wikipedia article on congruence. It's really easy to read and understand. And it has drawings, too. (ASA was not included in the list, but it is covered in the Wikipedia post with the other forms.)
What does sas mean in geometery?
In geometry, SAS stands for "side-angle-side," which refers to a method of proving congruence between two triangles. It states that if two sides and the included angle of one triangle are congruent to the corresponding sides and angle of another triangle, then the two triangles are congruent.
How do you compare and contrast triangles and a quadrilateral?
compare and contrast between triangles and a trapezoid
