Question

If a triangle has angles measuring 46", 51", and 83", what type of triangle is it? (1 point)

acute triangle

small triangle

O right triangle

Oobtuse triangle

Answer 1

To determine the type of triangle based on its angles, we can recall the following definitions:

- An **acute triangle** has all angles less than 90 degrees.
- A **right triangle** has one angle equal to 90 degrees.
- An **obtuse triangle** has one angle greater than 90 degrees.

Given the angles in the triangle: 46°, 51°, and 83°.

1. All of the angles (46°, 51°, and 83°) are less than 90°, so the triangle is not a right triangle.
2. All of the angles are also less than 90°, meaning it cannot be an obtuse triangle.

Since all three angles are less than 90 degrees, this triangle is classified as an **acute triangle**.

So the answer is: **acute triangle**.
