You write it exactly the same as you would write it in any other verions of C++, by taking user input to determine the three sides of your triangle. In other words, input three real numbers. What you do with those three numbers is entirely up to you, but presumably you'd want to calculate the angles of a triangle given the length of its three sides. For that you would need to use the cosine rule which states that for any triangle with angles A, B and C whose opposing sides are a, b and c respectively, cos A = (b2 + c2 - a2)/2bc and cos B = (c2 + a2 - b2)/2ca. Knowing two angles, A and B, you can easily work out that angle C must be 180 - (A + B).
What else can I help you with?
What is the name for a triangle that has two sides of equal length?
This triangle is called a scalene triangle.
Type of triangle with at least two sides congruent?
An isosceles triangle has 2 equal sides whereas an equilateral triangle has 3 equal sides.
How can you start the program 'read in the lengths of the sides of a triangle and determine whether the triangle is an isosceles triangle two sides are equal an equilateral triangle three sides are'?
This would depend on what programming language you wanted to write it in. For example, in Pascal, the code might look like this: Program Isosceles; Var A, B, C : Real; Begin WriteLn('Input side A.'); ReadLn(A); WriteLn('Input side B.'); ReadLn(B); WriteLn('Input side C.'); ReadLn(C); If A = B Then Begin If B = C Then Begin WriteLn('This triangle is equilateral.'); End Else Begin WriteLn('This triangle is isosceles.'); And so on.
What is an isoscles triangle?
A triangle with two angles of the same degree and the this one at a different degree.
What is the perimeter of triangle?
The perimeter of a triangle is the sum of its three sides.
How do you describe triangles by the sides?
Scalene Triangle- a triangle with no congruent sides Isosceles Triangle- a triangle with two congruent sides Equilateral Triangle- a triangle with three congruent sides
What type of triangle's sides have all nine sides?
A triangle can have only three sides. No triangle can have 9 sides!
What kind of triangle has no 2 sides equal?
Scalene Triangle: a triangle with no two sides equalIsosceles Triangle: a triangle with two sides equalEquilateral Triangle: a triangle with all sides equalRight Triangle: A triangle with two 'legs' vertex creates a 90o angle.
What is a triangle with at least two congurent sides?
A triangle with two congruent sides is an isosceles triangle, and a triangle with three congruent sides is an equilateral triangle.
What triangle has no congruent sides?
A scalene triangle has no congruent sides. An equilateral has all equal sides, and an isosceles triangle has two of three sides equal.
How is the equilateral triangle different from the isosceles triangle and scalene triangle?
They all have 3 sides but an equilateral triangle has 3 equal sides, an isosceles triangle has 2 equal sides and a scalene triangle has no equal sides.
How many sides are there on a triangle?
A triangle has three sides.
Triangle with no equal sides?
A triangle with no equal sides is called a Scalene Triangle.
A triangle with no two equal sides?
A triangle with no equal sides is a scalene triangle.
What triangle has 8 sides?
There is no such triangle. A triangle must have exactly 3 sides.
How many sides does an equaladeral triangle have?
A triangle - any triangle - has 3 sides.
What is a triangle with no congrent sides?
That is a scalene triangle. An isosceles triangle has at least 2 congruent sides and an equilateral triangle has 3 congruent sides.
