| Consider the case when the known length is the base.
Then the length of each of the remaining sides of the figure will be equal to:
(50 – 10): 2 = 20.
Let’s check the existence of such a triangle:
20 – 20 <10;
20 + 20> 10;
20 – 10 <20;
20 + 10> 20.
Exists.
The variant when the known side is side. Then the second side is also 10 cm.
Then the length of the base will be equal to:
50 – 10 * 2 = 30.
Let’s check the existence of such a triangle:
10 + 10 <30 (no such triangle exists)
Answer: 20 cm and 20 cm.
