How to Calculate Tri Angle

Introduction to how to calculate tri angle:

In mathematics, “tri angle” is nothing but a triangle. The triangle comes under the topic geometry. It is also in trigonometry. The triangles are made up of 3 lines. So, it consists of 3 angles and three sides. The triangle is calculated only based on their sides and also with angles. The triangles are classified into different types which are based on their sides and angles.

According to the sides and angles the triangles are classified as right triangles, acute triangles, obtuse triangles etc. To calculate the triangle we must need either the value of sides or angles. Here, we are going to calculate the area and perimeter of the triangle

How to calculate tri angle - Practice problem:

Let me help you in understanding on how to calculate Tri Angle with the following practice problem.

Problem 1: Calculate the area and perimeter of the triangle using heron's area formula Where sides a = 7, b = 9, c = 3, h = 5 and C = 60?

Answer is given below:

Therefore, the area and perimeter for this triangle is 39 and 19.

Problem 2: Calculate the area and perimeter of the triangle Where sides a = 8, b = 14, c = 2, h = 6?

Answer is given below:

Therefore, the area and perimeter for this triangle is 42 and 24.
