Finding the Unknown Cathetus Using the First Similarity Criterion

To find the unknown cathetus using the first similarity criterion, we can refer to the given figure and apply the relevant principles of similarity.

Step 1: Identify the Given Information - In the given figure, we have a right-angled triangle with two catheti and a hypotenuse.

Step 2: Apply the First Similarity Criterion - The first similarity criterion states that if in two triangles, corresponding angles are equal, then the triangles are similar. - In the given figure, we can identify the corresponding angles in the two triangles.

Step 3: Calculate the Unknown Cathetus - Using the first similarity criterion, we can set up the proportion to find the unknown cathetus.

Step 4: Solve for the Unknown Cathetus - By solving the proportion, we can find the value of the unknown cathetus.

Conclusion

By applying the first similarity criterion, we can find the value of the unknown cathetus in the given right-angled triangle.
