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, and Cis their … 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. So let's first look at included angles in geometry. In formal proofs, anytime … See more After studying this lesson, you are now able to identify the included angle for any two sides of any triangle, use included angles in geometric proofs of similarity and … See more WebThe included angle is the angle formed when two lines intersect at a point. The included angle can be either interior angle or exterior angle. If the bearing of lines is known, included angles can be calculated.
