Is there an analog to the SSS triangle congruence theorem for quadrilaterals?

## Answers (1) 2020-10-24
Step 1
To show whether there is an analog to the SSS triangle congruence theorem for quadrilateral.
Step 2
The SSS triangle congruence theorem states that if all 3 sides of one triangle are in proportion to all 3 sides of another triangle then those triangles are similar.
Step 3
It is observed that Side-Side-Side congruence is not sufficient to prove that two quadrilaterals are congruent. Since there are 4 parameters for a quadrilateral SSSS is possible.
Step 4
Therefore, there is no analog to the SSS triangle congruence theorem for quadrilateral.

In congruence classes $$\displaystyle\frac{{Z}}{{{m}{Z}}}$$, reduce the equation $$\displaystyle{a}_{{m}}\cdot{{x}_{{m}}^{{2}}}={c}_{{m}}$$ either by finding convenient representation for $$\displaystyle{a}_{{m}}{\quad\text{and}\quad}{b}_{{m}}$$ or by using the inverse of $$\displaystyle{a}_{{m}}$$. Then find a solution for this congruence directly or by replacing $$\displaystyle{c}_{{m}}$$ : with its appropriate representative in $$\displaystyle\frac{{Z}}{{{m}{Z}}}$$. If there is no solution explain why. Here $$\displaystyle{a}_{{m}},{b}_{{m}},{x}_{{m}}{\left(={x}\right)},{c}_{{m}}\in\frac{{Z}}{{{m}{Z}}}:$$
