**Congruent Triangles Worksheet Answers** – Triangles are among the fundamental shapes in geometry. Understanding the triangle is essential to learning more advanced geometric concepts. In this blog we will go over the different types of triangles, triangle angles, how to calculate the dimension and perimeter of the triangle, as well as provide examples of each.

## Types of Triangles

There are three kinds of triangulars: Equilateral isosceles, as well as scalene.

- Equilateral triangles have equal sides, and three angles of 60 degrees.
- Isosceles triangles have two equal sides and have two equal angles.
- Scalene triangles feature three distinct sides and three different angles.

Examples of each type of triangle will be shown.

## Triangle Angles

There are three angles in triangular shapes: acute right, and obtuse.

- Acute angles are less that 90 degrees.
- Right angles are precisely 90 degrees.
- Obtuse angles exceed 90 degrees.

Examples of each angle will be shown.

## Perimeter of Triangles

The perimeter of a triangle is the total of lengths along its three sides. To calculate the perimeter of a triangle, you have to add up the lengths of the three sides. The formula to calculate the perimeter of the triangle is:

Perimeter = Side A + Side B + Side C

A few examples of how to determine the perimeter of a triangle will be provided using various kinds of triangles.

## Area of Triangles

The size of a triangle is the amount of space that is contained within the triangle. To determine the dimensions of a rectangle, you have to know what the size of your base, as well as the diameter of the triangular. The formula to calculate the amount of space in a triangle:

Area = (Base x Height) / 2

Examples of how to determine the area of a triangle will be provided using various triangles.

## Conclusion

Understanding triangles is an essential element of learning about geometry. Understanding the different types of triangles, triangle angles, as well as how to calculate the perimeter and area of a triangle will help you to solve more difficult geometric problems. By using our comprehensive triangle worksheets you can boost your knowledge of these fundamental concepts and elevate your geometry skills to the next level.
