| **You are given real positive numbers a, b, c, which are the lengths of the sides of the triangle. Write a program that allows you to find the radius of the inscribed and circumscribed circles.**

program zz1;

var a, b, c, p: real; // set variables of non-integer type

begin

write (‘enter the first side of the triangle’);

read (a);

write (‘enter the second side of the triangle’);

read (b);

write (‘enter the third side of the triangle’);

read (c);

If a <b + c Then

If b <a + c Then

If c <a + b Then

begin

p: = (a + b + c) / 2;

Writeln (‘Inscribed circle radius =’, Sqrt (((p-a) * (p-b) * (p-c)) / p): 2: 2);

Writeln (‘Radius of the circumcircle =’, (a * b * c) / (4 * Sqrt ((p * (p-a) * (p-b) * (p-c)))): 2: 2);

end

Else Writeln (‘The triangle does not exist’);

END.
