Write a statement that must be true about an equilateral triangle and an isosceles triangle?
An equilateral triangle is also isosceles.Improved Answer:-They are both triangles whose 3 interior angles add up to 180 degrees and an equilateral triangle has 3 equal angles with 3 equal sides whereas an isosceles triangle has 2 equal angles with 2 equal sides
The side length of an equilateral triangle is x plus 3 write an expression for the perimeter of a triangle?
In an equilateral triangle, all 3 sides are the same length, so your equation would look something like this: P=the perimeter of the triangle (x+3)=length of each side P=3(x+3) If you wanted to simplify further, you would distribute the 3 to both the x and the 3 inside of the parentheses, giving you P=3x+9.
Write a Java program to determine whether the triangle is equilateral triangle?
import java.util.*; public class triangle { public static Scanner vic= new Scanner(System.in); public static void main(String[]args){ System.out.println("Enter measurement of adjacent: "); int adj = vic.nextInt(); System.out.println("Enter measurement of opposite: "); int opp = vic.nextInt(); System.out.println("Enter measurement of hypoteneuse: "); int hyp = vic.nextInt(); if(( adj < opp )&&(opp<hyp)){ System.out.println("Right triangle"); System.out.println("Regular triangle"); } else if (( adj<opp )&&( opp > hyp)){ System.out.println("Isosceles triangle"); } else if (( adj == opp)&&(adj==hyp)&&(hyp==opp)){ System.out.println("Equilateral triangle"); } else{ System.out.println("Not a triangle"); }} }
Triangle with 2 lines of symmetry?
A triangle with two lines of symmetry does not exist. It can have one line of symmetry (an isosceles triangle) or three (an equilateral triangle), but not two.
Write a general statement concerning the sum of the measures of the angles of a triangle?
The sum of the three interior angles of a triangle always total 180 degrees.
