Exercise 16 Page 387

Use a protractor to draw the given angles.

triangle with angles 95, 15, and 2 inch side
Practice makes perfect

We want to draw a triangle with a 95^(∘) angle connected to a 15^(∘) angle by a side of length 2 inches. First, we can use a ruler to draw a 2-inch side of our triangle.

To find the position of the third vertex, we can begin by drawing an angle of 95^(∘) using a protractor. Let's call the vertex of this angle A.
Angle of 95 degrees

Now we can draw the 15^(∘) angle with its vertex at the other point of the 2-inch side of our triangle. We can call this vertex B.

Angle of 15 degrees

The third vertex of our triangle is the point of intersection between the two rays. We can denote the vertex with C. Finally, we can draw a triangle with the given measures.
