Exercise 14 Page 387

We want to draw a triangle with side lengths of 1 inch and 2 inches that meet at a 50^(∘) angle. We can begin by drawing an angle of 50^(∘) using a protractor. Let's call the vertex of this angle A.

Next, we can use a ruler to mark 1 inch on one ray and 2 inches on the other ray. Let's start by marking 1 inch on one of the rays! We can do so using a ruler.

Now we can mark 2 inches on the other ray.

Next, we can draw the missing side using a ruler.

Finally, we can draw our triangle.
