![]() ![]() ![]() Therefore, the area of the scalene triangle is 42 square centimetres. Let us substitute the given values to the formula for finding the area of a triangle. With a base of 12 cm and a height of 7 cm, calculate the area of the scalene triangle. Therefore, the area of the scalene triangle is 25 square units. Let us use the formula, Area=½×base×h, to calculate the area of the given triangle. In the figure above, the height is the perpendicular distance from the base to the opposite vertex and notice that it forms a right angle with the base.Ĭalculate the area of a scalene triangle with a base of 10 units and a height of 5 units. The formula for calculating a scalene triangle’s perimeter uses the formula for calculating any triangle’s perimeter, which is the total of all the triangles’ side lengths. The total distance surrounding a triangle or its boundary is known as its perimeter. How do you determine the perimeter of a scalene triangle? These angles add up to a total of 180 degrees. One of the angles in a right scalene triangle is 90 degrees, while the other two are less than 90 degrees. The sides of a right scalene triangle are different in measure. The sum of the three angles is equal to 180 degrees. The sides of obtuse scalene triangles are different in measure.Īn obtuse scalene triangle has two other angles that are both less than 90 degrees and a third angle that is more than 90 degrees but less than 180 degrees. The sides of an acute scalene triangle are different in measure.Īn acute scalene triangle has acute angles of various measurement, adding up to 180 degrees in total. The comparison of the three varieties of scalene triangles according to their sides and angles is shown in the table below: Types of Scalene Triangles The angles A, B, and C also have different measurements. The hatch “|” symbol on each side denotes that each side has different measurements. The total of all interior angles of a scalene triangle is always equal to 180 degrees.Īn illustration of a scalene triangle is shown in the picture below. Scalene Triangle DefinitionĪ triangle with three different side lengths and three different angle measurements is called a scalene triangle. ![]() We shall discuss the description of the scalene triangle, its properties, and a few examples with solutions about its area and perimeter in this article. Triangles may be equilateral, isosceles, or scalene based on the lengths of sides. It can be classified based on its angle measurements or lengths of sides. What are examples of side lengths that form a scalene triangle?Ī triangle is a two-dimensional (2D) shape with three sides, three angles and three vertices.What are the different classifications of triangles?.What are the types of scalene triangles?.How do equilateral, isosceles, and scalene triangles differ from one another?.Frequently Asked Questions on Scalene Triangles.How to Identify Scalene Triangles Using Distance Formula?.How do you determine the perimeter of a scalene triangle?. ![]()
