Answer 1

To determine the type of triangle based on its angles, we note the following:

• An acute triangle has all angles measuring less than 90°.
• A right triangle has one angle that measures exactly 90°.
• An obtuse triangle has one angle that measures greater than 90°.

In the triangle with angles measuring 46°, 51°, and 83°:

• All angles are less than 90°.

Thus, this triangle is classified as an acute triangle.

So, the correct response is acute triangle.
