Included angle in triangle

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 WebSep 29, 2024 · Remember that the legs of a right triangle always meet at a right angle, so we always know the included angle between them.
