What is the definition of a triangle?

A triangle is a geometric shape that has three sides, three angles, and three vertices.

How many sides does a triangle have?

A triangle has three sides.

Are all three sides of a triangle always equal in length?

No, all three sides of a triangle are not always equal in length. In fact, there are different types of triangles based on their side lengths. An equilateral triangle has all three sides equal, while an isosceles triangle has at least two sides equal in length, and a scalene triangle has all three sides of different lengths.

What is an equilateral triangle?

An equilateral triangle is a geometric shape that has three equal sides and three equal angles, each measuring 60 degrees. This means that all sides of an equilateral triangle are the same length, and all angles are equal to each other.

Can a triangle have two sides of equal length?

Yes, a triangle can have two sides of equal length. This type of triangle is called an isosceles triangle, where two sides are equal in length. The third side, known as the base, can be a different length from the other two sides.

How many angles are there in a triangle?

There are three angles in a triangle.

What is the sum of the interior angles of a triangle?

The sum of the interior angles of a triangle is always 180 degrees. This property holds true for all triangles, regardless of their size or shape.

What is an acute triangle?

An acute triangle is a type of triangle in which all three angles are less than 90 degrees. This means that all angles in an acute triangle are considered acute angles, making the triangle itself smaller and more pointed compared to other types of triangles.

Can a triangle have one angle that is greater than 90 degrees?

No, a triangle cannot have one angle that is greater than 90 degrees because the sum of the interior angles of a triangle is always 180 degrees. If one angle is greater than 90 degrees, then the other two angles would have to be less than 90 degrees combined, which is not possible within the constraints of a triangle.

Can a triangle have all three angles equal to 90 degrees?

No, a triangle cannot have all three angles equal to 90 degrees because the sum of the angles in a triangle is always 180 degrees. If all three angles were 90 degrees, the total sum would be 270 degrees, which is not possible within a triangle.
