#### Congruence in Daily Life

Sometimes it can be difficult to replace your pen refill with a new one, and this is when the new refill is not the size you want to remove. If the two reloads are the same or conform, the new reload fits. Therefore, you can find many examples where object congruence is applied in everyday life situations.

##### Examples of Congruent Objects

You may wonder why we are studying greetings. Everyone must have seen a tray of ice in their fridge. Note that the snow molds are all greetings. The plaster used for casting in trays also has impermeable depressions (they can be rectangular or circular or all triangular). Therefore, whenever the same items must be produced, the concept of conformity is used to make molds.

###### Points to be remembered

- If two triangles and one triangle’s side are equal to two angles and the other triangle’s side is equal, then the two triangles are congruent (ASA Rule).
- If two triangles and one edge of a triangle are equal to two angles and the other is the corresponding side of the triangle, then the two triangles are congruent (AAS Rule).
- Angles opposite sides of a triangle are equal.
- The opposite sides of the angles are equal in a triangle.
