Exterior Angle Theorem In Triangle Worksheet

Exterior Angle Theorem In Triangle Worksheet – Triangles are one of the most fundamental shapes of geometry. Understanding the triangle is essential to learning more advanced geometric terms. In this blog post it will explain the different types of triangles and triangle angles, as well as how to determine the extent and perimeter of any triangle, and give specific examples on each.

Types of Triangles

There are three kinds for triangles: Equal isoscelesand scalene.

Equilateral triangles have three equally sides, and three angles of 60 degrees.

Isosceles triangles have identical sides and two equal angles.

Scalene triangles can be found with three sides, and three different angles.

Examples of each type of triangles will be presented.

Triangle Angles

Three angles are found in an arc: acute right, and obtuse.

Acute angles are less that 90 degrees.

Right angles are 90 degrees.

Obtuse angles are higher than 90 degrees.

A variety of angles will be provided.

Perimeter of Triangles

The perimeter of one of the triangles is simply the sum of lengths along its three sides. To calculate the perimeter of a triangular, you simply add the lengths of the three sides. The formula to calculate the perimeter of the triangle is

Perimeter = Side A + Side B + Side C

Examples of how to determine the perimeter of triangles will be demonstrated using various kinds of triangles.

Area of Triangles

The area of a triangular is the area of space within the triangle. To calculate the area of the triangle, you need to know that the distance between the bases as well as the size of the triangle. The formula for the amount of space in a triangle as follows:

Area = (Base x Height) / 2

A few examples of how to calculate the area of a triangle will be provided using various types of triangles.

Conclusion

Understanding the concept of triangles is an important part of learning geometric. Understanding the different types of triangles, triangle angles, and the methods to calculate the size and perimeter of the triangle can help you resolve more complicated geometric challenges. With our extensive triangle worksheets you can enhance your understanding of these core concepts and enhance your geometry capabilities to a higher level.
