Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
Let's add the three angles we are given and see what the sum is.
Add them together.
The three angles equal 180 degrees, therefore they can create a triangle.
Yes, 3 triangles have 180 degrees because the interior angles of a triangle must add to 180 degrees.
