The sum of the three interior angles of a triangle is always 180°.A triangle has three sides, three vertices, and three angles.The basic properties of a triangle are listed below: The perimeter of a triangle is equal to the sum of all three sides of the triangle.įAQs on Properties of Triangle What are the 5 Properties of a Triangle?.The basic formula for calculating the area of a triangle is Area (A) = (1/2) × Base × Height.We can classify various types of triangles in math by combining sides and angles. The sides and angles are very important aspects of a triangle.The triangle is a polygon that has three angles, three sides, and three vertices.For a triangle with sides a, b, and c, the semi-perimeter (s) = (a + b + c)/2, the area is given by A = \(\sqrt\) First, we need to calculate the semi-perimeter (s). Heron's formula: Heron’s formula is used to calculate the area of a triangle if the lengths of all the sides are known and the height of the triangle is not known.Perimeter: The perimeter of a triangle = sum of all its three sides.The basic formula for calculating the area of a triangle is Area (A) = (1/2) × Base × Height Area of a triangle: The total amount of space inside the triangle is called the area of a triangle.The basic triangle properties related to the area and perimeter of a triangle are given below. It should be noted that 3 exterior angles can be extended in a triangle and all these exterior angles add up to 360°.Īs per the Congruence Property, two triangles are said to be congruent if all their corresponding sides and angles are equal. In the given triangle, Exterior angle (e) = ∠a + ∠b Thus, the side AC is the longest side.Īs per the exterior angle theorem, the exterior angle of a triangle is always equal to the sum of the interior opposite angles. In this triangle, ∠B is the greatest angle. In order to understand this property which says that the side opposite the greater angle is the longest side, observe the triangle given below. Side Opposite the Greater Angle is the Longest Side Observe the figure given below to see the altitude, the base, and the hypotenuse. Mathematically, it can be expressed as Hypotenuse² = Base² + Altitude². If a = 4 units, b = 6 units, c = 3 units, let us verify the triangle inequality property as follows:Īs per the Pythagoras theorem, in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Observe the figure given above which shows △ABC which represents the Triangle inequality property. In the given triangle, ∠P + ∠Q + ∠R = 180° Triangle Inequality PropertyĪs per the triangle inequality theorem, the sum of the length of the two sides of a triangle is greater than the third side. Angle Sum PropertyĪs per the angle sum property, the sum of the three interior angles of a triangle is always 180°. Some of the important properties of a triangle are listed below. The properties of a triangle help us to identify relationships between different sides and angles of a triangle.
