Explain why you can not use angle angle angle to prove two triangles are congruent?
Knowing that three angles are congruent only proves that two triangles are similar. Consider, for example, two equilateral triangles, one with sides of length 5 and the other of lengths ten. Both have three angles of 60 degrees each, but they are not congruent because their sides are not of the same length.

What does angle angle side mean?
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
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.
What is the angle-angle-side rule?
Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.
What arrangement cannot be used to prove two triangles congruent?
The SSA (Side-Side-Angle) arrangement cannot be used to prove two triangles congruent. This is because knowing two sides and a non-included angle does not guarantee that the triangles are congruent, as it can lead to ambiguous cases where two different triangles can be formed. In contrast, arrangements like SSS (Side-Side-Side), SAS (Side-Angle-Side), or AAS (Angle-Angle-Side) can definitively establish congruence.
Can you use the ASA Postulate or the AAS Theorem to prove the triangles congruent?
Yes, you can use either the ASA (Angle-Side-Angle) Postulate or the AAS (Angle-Angle-Side) Theorem to prove triangles congruent, as both are valid methods for establishing congruence. ASA requires two angles and the included side to be known, while AAS involves two angles and a non-included side. If you have the necessary information for either case, you can successfully prove the triangles are congruent.
What else must you know to prove the triangles congruent by SAS?
Nothing. If a side ,an angle, and a side are the same the triangles are congruent.
What does angle angle side mean?
Angle Angle Side is a method one can use to prove that two triangles are congruent. Basically, if any two pairs of angles and the side between these angles are congruent, then the triangles are congruent as well.
What are the five ways to prove a triangles congruent?
The 5 ways to prove that two triangles are congruent are to find equal: 1) side-side-side 2) side-angle-side 3) angle-side-angle 4) angle-angle-angle 5) hypotenuse-leg
What are three ways that you can prove that triangles are congruent?
If triangles have the corresponding sides congruent then they are congruent. SSS If two triangles have two sides and an included angle congruent then they are congruent. SAS If two triangles have two angles and an included side congruent then they are congruent. ASA SSA doesn't work.

How do you prove something is congruent with the form SAS?
Show that, if you have two triangles, two of the sides and the angle in between are congruent.
What is the angle-angle-side rule?
Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.

In contrast, arrangements like SSS (Side-Side-Side), SAS (Side-Angle-Side), or AAS (Angle-Angle-Side) can definitively establish congruence.
What is the sss rule?
if you have two triangles you can prove them congruent by stating that all of the sides are congruent, hence (SSS=Side, Side, Side). You can also do the same by stating SAS (Side, Angle, Side) or ASA (Angle, Side, Angle). Using these methods, everything must be in order and consecutive to prove the triangles congruent good question
Can you use the ASA Postulate or the AAS Theorem to prove the triangles congruent?
Yes, you can use either the ASA (Angle-Side-Angle) Postulate or the AAS (Angle-Angle-Side) Theorem to prove triangles congruent, as both are valid methods for establishing congruence. ASA requires two angles and the included side to be known, while AAS involves two angles and a non-included side. If you have the necessary information for either case, you can successfully prove the triangles are congruent.
What theorem can you use to prove triangles are similar?
You can use the Angle-Angle (AA) Similarity Theorem to prove that triangles are similar. According to this theorem, if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This is because the third angle will also be congruent, ensuring that the corresponding angles are equal, which in turn implies that the sides are in proportion.
How would you prove triangles are 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.
