In an isosceles triangle, some side is 38 cm, and some 19 cm Find out what the base of the triangle is.

So, in an isosceles triangle, one side is 38 cm, and the other is 19 cm. In order to find which side is the base, we recall the conditions under which the triangle can exist.

A triangle exists if the sum of the lengths of the two sides of the triangle is always greater than the third.

If the base is 38 cm, then the sides are 19 cm.

19 + 19 = 38 (the condition is not met).

If the base is 19 cm, and the sides are 38 cm, then

38 + 38> 10;

19 + 38> 38, the condition is met.

Answer: the base is 19 cm; side 38 cm.
