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.

Postulate or theorem used to prove two triangles are congruent?

You can use a variety of postulates or theorems, among others: SSS (Side-Side-Side) ASA (Angle-Side-Angle - any two corresponding sides* and a corresponding angle) SAS (Side-Angle-Side - the angle MUST be between the two sides, except:) RHS (Right angle-Hypotenuse-Side - this is only ASS which works) * if two corresponding angles are the same, then the third corresponding angle must also be the same (as the angles of a triangle always sum to 180°), and that can be substituted for one angle of ASA to get AAS or SAA.


How can you used a triangle to prove quadrilateral is a parallelogram?

A quadrilateral, in general, is not a parallelogram. If it is a parallelogram then you will have some additional information about its sides and angles. If you do not have such information it is not possible to prove that it is a parallelogram. Draw a diagonal which will divide the quadrilateral into two triangles and use the additional information that you have to show that the triangles are congruent. This can then be used to show equality of sides or of angles: the latter can then be used to show that sides are parallel. Note that the choice of which diagonal may influence how (if at all) you proceed.

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 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 are congruent triangles used in real life?

Congruent triangles are used in real life in various fields such as architecture, engineering, and design. In architecture, congruent triangles are used to ensure stability and balance in structures. In engineering, they are used to calculate forces and angles in different structures. In design, congruent triangles are used to create symmetrical and aesthetically pleasing patterns. Overall, understanding congruent triangles is crucial for ensuring accuracy and precision in real-life applications.

AAA, or angle angle angle, is a postulate used to prove the similarities of two triangles. If there exists a correspondence between the vertices of two triangles such that the three angles of one triangle are congruent to the corresponding angles of the other triangle, then the triangles are similar.
