Yes. In fact, there has to be at least two. Acute angles are angles less than 90 degrees.

### What is the difference between an acute triangle and an obtuse triangle?

An acute triangle has three interior acute angles An obtuse triangle has one obtuse and two acute interior angles

### Is there a minimum number of acute interior angles that any polygon can have?

Although a triangle must have at least two acute interior angles, a square has four interior right angles and no acute angles. And as regular polygons have increasing numbers of sides, their interior angles get larger.

### What is a righgt triangle?

A right angle triangle has a 90 degree angle and two interior acute angles

### Why does a triangle have two acute angles?

If there were less than two acute angles, there would be two (or more angles that were 90 degrees or more. Then the sum of the three angles of the triangle would be more than 180 degrees. But this is not possible because the interior angles of a triangle sum to 180 degrees.

### Why a triangle should have at least two acute angles?

Because the 3 interior angles of any triangle add up to 180 degrees.

### Can a triangle have one acute angles?

nope. if it did, the two other ends wouldn't be able to meet with obtuse angles. A triangle must have two or three acute angles. A triangle always has interior angles that sum to 180 degrees. If a triangle had only one acute angle, the sum of its angles would be more than 180 degrees, which is not possible.

### Does a obtuse triangle have two acute angles?

yes an obtuse triangle has two acute angles

### Why do you know that a right triangle has no obtuse interior angles?

Because the 3 interior angles of a triangle add up to 180 degrees and if one of those angles is a right angle then the other two angles must be acute angles.

### Are all triangles have 2 acute angles?

Yes, that is the least amount of acute angles a triangle may posses, but a triangle may also have three acute angles. The sum of all triangles' interior angles are equal to 180 degrees; therefore, it is physically impossible to have less than two acute angles, yet entirely possible to contain two or three acute angles.

### Can a right triangle have two acute angles?

A right angled triangle can only have two acute angles.

### Does an acute triangle have two right angles?

No, in fact no triangle can have two right angles. The sum of all interior angles of any triangle is 180 degrees. All triangles must have three angles. A right angle is 90 degrees. So if a triangle has two ninety degree angles, there would be no third angle. An acute triangle has all three angles less than 90 degrees. The most common acute triangle is the equilateral 60-60-60 degree triangle.

### What is the greatest number of acute angles right triangle can contain?

Two. Two acute angles in a right triangle.
