List the names of the things of triangle-shaped objects?

A triangle is a closed two-dimensional polygon with three sides and a total angle of 180 degrees.

THE MANY TYPES OF TRIANGLES

To classify triangles on the basis of their angles, we evaluate each of their inner angles, and then the triangles are classified as follows:

• An acute-angled triangle is one in which all of the inner angles are acute (less than 90 degrees).
• Triangle with a Right Angle: A right-angled triangle has a right angle ( angle = 90°).
• A triangle with one obtuse angle (more than 90°) is called an obtuse-angled triangle.

Classification based on sides

We calculate the length of every side of a triangle for classification, and triangles can be categorized by their sides as follows:

1. Equilateral Triangle: An equilateral triangle is one in which all three sides of the triangle have the same length. Due to this, all the three angles are also the same. All the angles of an Equilateral Triangle are 60 degrees.
2. Isosceles Triangle: An isosceles triangle is a triangle with two sides having an equal length and the third side of a different length. The angles on the opposing sides of the equal sides are the same.
3. Scalene Triangle: A scalene triangle is a triangle with three sides of varying lengths. Because the three sides have varying sizes, the three angles will have different values as well.
