**Triangle Congruent Worksheet** – Triangles are one of the most fundamental designs in geometry. Understanding triangles is critical to learning more advanced geometric terms. In this blog, we will cover the different types of triangles, triangle angles, how to calculate the dimensions and the perimeter of a triangle, and provide an example of every.

## Types of Triangles

There are three kinds in triangles, namely equilateral, isosceles, as well as scalene.

- Equilateral triangles have three equally sides as well as three angles of 60 degrees.
- Isosceles triangles have equally sized sides as well as two angles.
- Scalene triangles are made up of three sides, and three different angles.

Examples of each type of triangle will be provided.

## Triangle Angles

Three angles are found in a triangle: acute, right, and obtuse.

- An acute angle is less than 90 degrees.
- Right angles are precisely 90 degrees.
- Obtuse angles are those that are greater than 90 degrees.

A variety of angles will be given.

## Perimeter of Triangles

The perimeter of a triangle is the sum that of the dimensions of its angles. To determine an area of perimeter in a triangular, one adds the lengths of its three sides. The formula for calculating the perimeter of one of these triangles is

Perimeter = Side A + Side B + Side C

A few examples of how to determine the perimeter of triangles will be demonstrated using different types of triangles.

## Area of Triangles

The surface of a Triangle is the amount of space inside the triangle. To calculate the size of a triangle you need to know how long the bottom as well as the dimensions of the triangle. The formula for calculating the dimension of an area in triangles are:

Area = (Base x Height) / 2

A few examples of how to calculate the area of an arc will be shown using different types of triangular shapes.

## Conclusion

Understanding the importance of triangles is a crucial element of learning about geometry. Knowing the different types of triangles, angles, and the methods to calculate the size and perimeter of the triangle can assist you in solving more complex geometric problems. Through our extensive set of triangle worksheets, students can increase the understanding of these basic concepts and elevate your geometry skills to the next level.
