Title: Triangle Classification: Check All That Apply

Introduction:
Triangles are simple yet versatile geometric shapes that have been studied for centuries. They are defined by their three sides and three angles, and can be classified into various types based on their properties. In this article, we will explore the different classifications of triangles and discuss the characteristics that define them.

1. Equilateral Triangle:
An equilateral triangle is a type of triangle where all three sides are equal in length. Additionally, all three angles in an equilateral triangle are also equal, measuring 60 degrees each. This makes it a regular polygon with symmetrical properties.

2. Isosceles Triangle:
In an isosceles triangle, two sides are of equal length while the third side is different. This means that two angles in an isosceles triangle are also equal, forming a base angle opposite the unequal side. The third angle, known as the vertex angle, is always different from the base angles.

3. Scalene Triangle:
A scalene triangle is characterized by having no sides of equal length. Each side has a different measurement, resulting in three distinct angles as well. Unlike equilateral or isosceles triangles, there are no congruent angles or sides in a scalene triangle.

4. Right Triangle:
A right triangle contains one right angle (90 degrees). This special angle occurs when one of the triangle’s angles forms a perfect perpendicular intersection between its two adjacent sides. The other two angles in a right triangle will always be acute (less than 90 degrees).

5. Acute Triangle:
An acute triangle consists of three acute angles, meaning all three angles measure less than 90 degrees. In other words, none of the angles within an acute triangle form a right angle or extend beyond it.

6. Obtuse Triangle:
An obtuse triangle possesses one obtuse angle that measures greater than 90 degrees but less than 180 degrees. The other two angles are acute, totaling less than 90 degrees combined.

Summary:
In conclusion, triangles can be classified into various types based on their properties. An equilateral triangle has three equal sides and angles, while an isosceles triangle has two equal sides and angles. A scalene triangle has no equal sides or angles. A right triangle contains one right angle, while an acute triangle includes three acute angles measuring less than 90 degrees each. Lastly, an obtuse triangle features one obtuse angle greater than 90 degrees but less than 180 degrees. Understanding these classifications helps in identifying and analyzing different geometric shapes in real-world applications or mathematical problem-solving scenarios.
