Step 2: To find the value of the smaller angle, we will use the law of sinesĪngle B is smaller than Angle C as Angle B is opposite to the shorter side. Step 1: To find the value of 'a' let us use the Law of Cosines Let us follow the steps of the side angle side formula: Let us name side AB as c, and side AC as b

Given: side 1 = 5 cm, side 2 = 10 cm, sin (included angle) = sin 30° = 1/2Īnswer: Thus, the area of the triangle is 12.5 cm 2Įxample 2: In the triangle shown below, find all the dimensions using the side angle side formula. We know that the side angle side formula is given as:

Math will no longer be a tough subject, especially when you understand the concepts through visualizations with Cuemath.īook a Free Trial Class Examples Using Side Angle Side FormulaĮxample 1: What will be the area of a triangle whose sides are of length 5 cm and 10 cm and its included angle is 30°? Let us work on some problems to understand the side angle side formula. Therefore, the side angle side formula or the area of the triangle using the SAS formula = 1/2 × a × b × sin c Step 4: Since p = a × sin c, the formula for the area of the triangle will be = 1/2 × b × a × sin c.Substituting the value of base as b and height as p, the area of the triangle will be = 1/2 × b × p. Step 3: Since we know that the area of a triangle = 1/2 × base × height.Step 2: If we draw a perpendicular 'p' from X to side YZ, then using the trigonometric ratio, we can write the value of p as, p = a × sin c considering p as the height, and applying the formula Sin c = p/a.Step 1: If the two given sides are 'a' and 'b' and the included angle between them is 'c'.So, let us consider the following triangle to understand the derivation of the SAS formula using the steps given below. We know that the area of a triangle is = 1/2 × base × height. The angle between the two sides is known as the included angle.

According to the Side Angle Side theorem, two triangles are said to be congruent if two sides and the angle that lies between these two sides are equal. The side angle side formula was created on the basis of the Side Angle Side Theorem. The SAS formula is expressed as:Īrea of a triangle = (1/2) × side 1 × side 2 × sin (included angle) The side angle side formula is the SAS area formula which means we can find the area of a triangle if the length of two sides of a triangle and its included angle is known. Let us explore more about the side angle side formula to calculate the area of a triangle. As the name suggests, side angle side represents the two sides and the angle between them. This formula which is based on the side angle side theorem helps us to calculate the area of a triangle. The side angle side formula which is also known as the SAS formula is used to calculate the area of the triangle using trigonometry rules.
