Classifying Triangles Worksheet Homeschool.net – Triangles are one of the fundamental shapes in geometry. Knowing how triangles work is essential to understanding more advanced geometric concepts. In this blog we will go over the various kinds of triangles such as triangle angles, and how to calculate the extent and perimeter of any triangle, and give illustrations of all.
Types of Triangles
There are three types in triangles, namely equilateral isosceles, and scalene.
- Equilateral triangles have three equally sides and three angles of 60 degrees.
- Isosceles triangles have two equal sides and have two equal angles.
- Scalene triangles can be found with three sides and three different angles.
Examples of each type of triangle are provided.
Triangle Angles
There are three angles in an triangle: acute right, and obtuse.
- Acute angles are angles that are less than 90 degrees.
- Right angles are 90 degrees.
- Obtuse angles are greater than 90 degrees.
An example of each angle will be shown.
Perimeter of Triangles
The perimeter of a triangle is the total of the lengths of its sides. To calculate it’s perimeter triangle you simply add the lengths of its three sides. The formula to calculate the perimeter of a triangle is:
Perimeter = Side A + Side B + Side C
A few examples of how to determine the perimeter of the triangle will be presented using different triangles.
Area of Triangles
The space of a rectangle is the amount of space inside the triangle. To determine the dimensions of a rectangle, you will need to know that the distance between the bases, as well as the diameter of the triangular. The formula to calculate the dimensions of a triangular area is:
Area = (Base x Height) / 2
A few examples of how to determine the area of an individual triangle will be demonstrated using different types of triangular shapes.
Conclusion
Understanding the concept of triangles is an important element in learning geometry. Knowing the different kinds of triangles, triangle angles, and the methods to calculate the length and width of a triangle can help solve more complicated geometric challenges. By using our extensive triangle worksheets you can boost the understanding of these basic concepts and elevate your geometry ability to the next level.
