While tooth decay is often the primary cause of a toothache, it's important for you to have a complete oral examination to determine the cause. Other causes of a toothache can include the following: 1  Infection. 2  Gum disease. 3  Grinding teeth (bruxism). 4  Tooth trauma. 5  An abnormal bite.
Thus the formal definition of corresponding sides can be stated as follows: In two or more different plane figures, the sides that are in the same position but in different plane figures are called corresponding sides.
Answer: You are not given a single pair of corresponding sides so you cannot find the similarity ratio. Remember: How to Find corresponding sides. Corresponding sides follow the same letter order as the triangle name so: 1  YZ of $$ \triangle X\color{red}{YZ}$$ corresponds with side KL of$$\triangle J\color{red}{KL} $$. 2  JK of $$ \triangle \color{red}{JK}L $$ corresponds with side XY of$$\triangle \color{red}{XY}Z $$.
