What is an equilateral triangle?

An equilateral triangle is a triangle with all three sides of equal length and all three angles measuring 60 degrees. It is considered a special type of triangle due to its symmetry and properties, making it unique among other geometric shapes.

What is an isosceles triangle?

An isosceles triangle is a type of triangle that has two sides of equal length. This means that two of its three sides are the same length, while the angles opposite those sides are also equal in measure.

What is a scalene triangle?

A scalene triangle is a type of triangle that has three sides of different lengths and three angles of different measures. It does not have any sides or angles that are equal in length or measure.

What is a right triangle?

A right triangle is a triangle in which one of the angles is a right angle, measuring 90 degrees. This means that the two sides that meet at the right angle are perpendicular to each other. The side opposite the right angle is known as the hypotenuse, while the other two sides are called the legs of the triangle.

What is an acute triangle?

An acute triangle is a triangle in which all three angles are less than 90 degrees. This means that the triangle is sharp or narrow, with its vertices forming acute angles.

What is an obtuse triangle?

An obtuse triangle is a triangle that has one angle measuring more than 90 degrees. This means that one of the three angles in an obtuse triangle is greater than a right angle, which is 90 degrees.

What is a congruent triangle?

A congruent triangle refers to two triangles that are identical in shape and size, with all corresponding angles equal and all corresponding sides equal in length. This means that if you were to place one triangle on top of the other, they would completely overlap. Congruent triangles have the same area and perimeter, making them essentially the same triangle in terms of measurements and dimensions.

What is an exterior angle of a triangle?

An exterior angle of a triangle is an angle formed when one side of the triangle is extended. It is equal in measure to the sum of the two interior angles that are not adjacent to it.

What is an interior angle of a triangle?

An interior angle of a triangle is an angle formed inside the triangle by two adjacent sides. Each triangle has three interior angles, and the sum of all interior angles in a triangle is always 180 degrees.

What is a triangle inequality theorem?

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. In other words, in a triangle with sides of lengths a, b, and c, where a and b are the two shorter sides, the sum of a and b must be greater than c in order for the triangle to be valid. This theorem is a fundamental property of triangles in Euclidean geometry.
