WebArea of equilateral triangle $= \frac{\sqrt{3}a^2}{4}$ square units. Using Two Sides and Included Angle (SAS) Formula. How are the angles of an equilateral triangle related to its … WebIt is also good to remember that the angle is always between the two known sides, called the "included angle". How Does it Work? We start with this formula: Area = ½ × base × height We know the base is c, and can work out the height: the height is b × sin A So we get: Area = ½ × (c) × (b × sin A) Which can be simplified to: Area = 1 2 bc sin A
Trigonometry allows you to find properties of triangles, like area, using only the relationships between sides and angles. While geometry provides a formula for area, A=12bhA=\frac{1}{2}bhA=21bh, trigonometry provides a different one, where A = area of the triangle, a and b are lengths of sides, … See more An included angle is the angle between two line segments or rays. For any triangle, its three interior angles are each included between two sides. Draw or imagine an … See more Most mathematics students find geometry a bit easier to comprehend than trigonometry.
