Answer:

import java.util.Scanner; public class KboatTriangleAngle { public static void main(String args[]) { Scanner in = new Scanner(System.in); System.out.print("Enter first angle: "); int a1 = in.nextInt(); System.out.print("Enter second angle: "); int a2 = in.nextInt(); System.out.print("Enter third angle: "); int a3 = in.nextInt(); int angleSum = a1 + a2 + a3; if (angleSum == 180 && a1 > 0 && a2 > 0 && a3 > 0) { if (a1 < 90 && a2 < 90 && a3 < 90) { System.out.println("Acute-angled Triangle"); } else if (a1 == 90 || a2 == 90 || a3 == 90) { System.out.println("Right-angled Triangle"); } else {
