Explanation: Convert each of the three measures to the same unit; we will choose the smallest unit, inches. Where sides a, b, c, and angles A, B, C are as depicted in the above calculator, the law of sines can be written as shown below. Identify the base. In what follows we'll: Recall there are three types of angles that you can encounter while dealing with triangles: Based on that, we distinguish three types of triangles: Acute triangles can be further divided into three categories, based on the side lengths (more precisely, on side length ratio): As you see, once we understand what an acute triangle is, it's obvious how to decide if a triangle is acute if you know its angles: just take a look at these angles and make sure they are all strictly less than 90 (/2 rad). There are many ways to find the height of the triangle. Every side of the triangle can be a base; there are three bases and three heights (altitudes). b=h2+ a2 4 =tan1(2h a) S = 1 2ah b = h 2 + a 2 4 = t a n 1 ( 2 h a) S = 1 2 a h select elements base a height h For instance, if one of the angles is 91, the sum of the other two angles will be 89. This calculator solves the Pythagorean Theorem equation for sides a or b, or the hypotenuse c. The hypotenuse is the side of the triangle opposite the right angle. Calculate the heights of the triangle from its area. In a right triangle, the side that is opposite of the 90 angle is the longest side of the triangle, and is called the hypotenuse. Let's see what they are: Property 1: The longest side of a triangle is the side opposite to the obtuse angle. This calculator solves the Pythagorean Theorem equation for sides a or b, or the hypotenuse c. The hypotenuse is the side of the triangle opposite the right angle.
