If a triangle has angles measuring 46º , 51º, and 83º, what type of triangle is it?
acute
right
small
obtuse
The sum of the angles in any triangle is always 180 degrees. Therefore, in this triangle, the sum of the angles would be 46 + 51 + 83 = 180.
Since none of the angles are equal to or greater than 90 degrees, the triangle is not a right triangle.
The largest angle in this triangle is 83 degrees, which is greater than 90 degrees. Therefore, this triangle is an obtuse triangle.
