To calculate any side, a, b or c, say b, enter the opposite angle B and then another angle-side pair such as A and a or C and c. The performed calculations follow the angle angle side (AAS) method and only use the law of sines to complete calculations for other unknowns. A = 0.5 * r squared * (((PI/180) * Θ) - sin (Θ)) where Θ is the angle. So, the only solution is to start making methodical guesses at Θ and see if the area calculated matches what you are expecting (within a certain tolerance). And given that the percentage will be less than 50 (and greater than 0) then: 0 < angle < 180.

The central angle of a circle is the angle based at the circle's center. In other words, the vertex of the angle must be at the center of the circle. A central angle is formed by two radii that start at the center and intersect the circle itself. angle = acos (v1•v2) axis = norm (v1 x v2) If the vectors are parallel (angle = 0 or 180 degrees) then the length of v1 x v2 will be zero because sin (0)=sin (180)=0. In the zero case the axis does not matter and can be anything because there is no rotation round it.

Angles in a circle. 2. Chord properties . 3. Tangent properties. 4. Circles and circumference . 5. Arcs of a circle. 6. Areas and sectors of circles. 7. Central angles and proofs. 8. Inscribed angles and proofs. 9. Central and inscribed angles in circles. 10. Circle chord, tangent, and inscribed angles proofs. Back to Course Index The deflection from the tangent for a chord of length c is half the central angle, or δ = d/2. This is a general rule, so additional 100 ft chords just increase the deflection angle by D/2. Therefore, it is very easy to find the deflection angles if a round value is chosen for D, and usually easy to set them off on the instrument.

The area has no relevance to find the angle of a regular hexagon. There are 6 sides in a regular hexagon. Use the following formula to determine the interior angle. Substitute sides to determine the sum of all interior angles of the hexagon in degrees. Since there are 6 sides, divide this number by 6 to determine the value of each interior angle.
