I can easily write three test cases: a valid input for a scalene triangle, a valid input for an isosceles triangle, and a valid input for an equilateral triangle. An isosceles triangle is a triangle where any two sides of a triangle should be equal both in terms of length and angles. Let's start with the sides being positive. I know that a set of test cases doesn’t have complete coverage if it doesn’t include at least one case for each program output.
Now, you want to write tests for type() You then edit type() until your tests succeed. public String toString () - Prints the sides of the triangle. public boolean isscalene () - Determines whether a triangle is scalene. Any (and at least) two sides must be equal. Next, you need a way to distinguish between the different types of triangles. Determines whether a triangle is isosceles. The JUnit test run tells you which of your test numbers is failing. an equilateral, isosceles or scalene triangle). Thus, 65 is the base angle and 50 is the vertex angle. Program If you’re curious to see the Triangle Problem code, then the link is here with tested test cases. Valid types - You will receive credit for submitting a test set for a correct implementation of the triangleType method from the class provided (i.e.

Now, I went through and tried figuring out how to calculate those other two endpoints of the triangle so I could make the polygon, but I am not doing it correctly because I am getting a triangle that isn't isosceles and the endpoints don't create a line perpendicular to the original line.First, you need to know the conditions for three numbers being the sides of a triangle. An equilateral triangle is a special case of the isosceles triangle, where all three sides and angles of the triangle are equal. An isosceles triangle has one vertex angle and two congruent base angles. Also the sides across from congruent angles are congruent. (Would put direct images but don't have enough rep) SAT Math : Equilateral Triangles - Varsity Tutors. Question 3: 1 pts In an isosceles triangle, the angles across from the congruent sides are congruent. This crude paint drawing should help figure out what I am talking about I have been trying to figure this one out for some time now, I am making a program that uses a triangle as an arrow and been trying to figure out how to make an arrow with two points, meaning that that the first point would be at the midpoint of the base of the triangle, while the second point would be at the tip facing the direction away from the first point.
