Question

What kind of triangle is this?

35°
105°
40°

Answer 1

To classify the triangle based on the given angles, we first need to confirm that the angles sum up to 180°.

The given angles are:
- 35°
- 105°
- 40°

Now, let's add them up:

35° + 105° + 40° = 180°

Since the angles do sum up to 180°, it confirms that these angles can form a triangle.

Now, to classify the triangle based on the angles:
- An acute triangle has all angles less than 90°.
- A right triangle has one angle that is exactly 90°.
- An obtuse triangle has one angle that is greater than 90°.

In this case:
- 35° is acute
- 105° is obtuse (greater than 90°)
- 40° is acute

Since there is one obtuse angle (105°), the triangle is classified as an **obtuse triangle**.
