Here is the Java program to find the area of a Right Angled Triangle. To calculate the area of a Right-angled triangle, first we need to understand some fundamental properties of a right angled triangle. Right triangle is a triangle in which one angle is a right angle (90 degree). The sum of the other two angles of right-angled triangle is 90 degree.
Sides of Right Triangle
- Base and Perpendicular : The two adjacent sides of the right angle. These are the two sides of a triangle which are not hypotenuse.
- Hypotenuse : Hypotenuse is the longest side of a right angled triangle which is opposite the right angle.
Area of Right angled Triangle
Area of Right triangle, if we know the length of base and perpendicular.
If we know the length of hypotenuse and altitude of a right triangle, then we can use below mentioned formula to find area of a right triangle.
Area of Right triangle, if we know the length of base and perpendicular.
- Area of Right Triangle = (1/2)* Base * Perpendicular
If we know the length of hypotenuse and altitude of a right triangle, then we can use below mentioned formula to find area of a right triangle.
- Area of Right Triangle = (1/2)* Hypotenuse * Altitude
Java program to calculate area of right triangle
package com.tcc.java.programs;
import java.util.*;
class TriangleArea {
public static void main(String args[]) {
double base, height, area;
Scanner in = new Scanner(System.in);
System.out.println("Enter length of base of Triangle");
base = in.nextDouble();
System.out.println("Enter length if height of Triangle");
height = in.nextDouble();
// Area if Triangle = (Base X Height)/2;
area = (base * height)/2;
System.out.println("Area of Triangle = " + area);
}
}
Output
Enter length of base of Triangle 3.0 Enter length if height of Triangle 4.0 Area of Triangle = 6.0
