Question

Which theorem can you use to prove the two triangles are similar? 

The image depicts two nested right-angled triangles labeled as follows:

1. The larger triangle is ∆HJK with vertices at points H, J, and K.
2. The smaller triangle is ∆RST with vertices at points R, S, and T. The smaller triangle lies within the larger triangle, sharing the right angle at point T.

Key dimensions and angles are labeled:
- In the larger triangle ∆HJK:
  - The hypotenuse HJ is 10 units.
  - The leg JK is 8 units.
  - The leg HT is unlabeled.

- In the smaller triangle ∆RST:
  - The hypotenuse RS is 6 units.
  - The leg ST is 4.8 units.
  - The leg RT is unlabeled.

Additionally, the diagram indicates that the angles ∠HTK and ∠JST are equal, suggesting a similarity between the two triangles.

This detailed breakdown of the geometric figure is used to illustrate the concept of similar triangles and their properties, particularly focusing on the proportionality of the corresponding sides and angles. This can be useful in an educational setting to apply and understand the properties of similar triangles and theorems related to right-angle triangles.
