We want to determine whether we can construct one, many, or noisosceles triangles with two side lengths of 4 inches that meet at an 80^(∘) angle. We can begin by drawing an angle of 80^(∘) using a protractor.
Next, we can use a ruler to mark 4 inches on one ray and 4 inches on the other ray. Let's start by marking 4 inches on one of the rays! We can do so using a ruler.
Now we can mark 4 inches on the other ray.
Finally, we can draw the missing side using a ruler.
Notice that there is only one way to draw the line segment between the endpoints of the given sides. This means that there is only triangle with the given description.
