Answer:
The triangles are congruent as they both have sides lengths (15, 20, 25)
a = 25
b = 20
c = 15
d = 20
e = 20
f = 15
Step-by-step explanation:
For the first triangle, using Pythagorean Theorem, the length of the missing side is:
![\sqrt[]{15^2+20^2}=25](https://img.qammunity.org/2023/formulas/mathematics/college/s3qc08udc7rywdwwmriy289xxfq70orqva.png)
For the second triangle, the length of the missing side is:
![\sqrt[]{25^2-20^2}=15](https://img.qammunity.org/2023/formulas/mathematics/college/z0e5zd0bo8gjs7qc0bawjn1uggw3ykionn.png)
These triangles are congruent as they both have sides lengths (15, 20, 25)
