Use a protractor to draw the given angles.
We want to draw a triangle with a 70^(∘) angle connected to a 70^(∘) angle by a side length of 4 centimeters. First, we can use a ruler to draw a 4-centimeter side of our triangle.
Now we can draw the 70^(∘) angle with its vertex at the other point of the 4-centimeter side of our triangle. We can call this vertex B.
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.
