WebSep 16, 2024 · The intercepted arc of a convex central angle is also known as minor arc because it is less than 180 degrees. The remaining portion of the circle is called a major … WebThis means that when we make the diameter across the circle, what it creates is a triangle with two sides equal to the radius. For example psi one, has one radius spanning towards the center, and another side which comes from the center of the circle to another point of the circumference of the circle. check website name availability https://cleanbeautyhouse.com

WebA section or part of a circle involved by two radii with a central angle of 180 ∘ is called a semicircle. The combination of any two hands (minute hands and hour hands or hour hands and second hands or minute hands and second hands) of a circular analog clock form sectors. Conclusion WebThe semicircle is bounded at the diameter. The angle made by the diameter at the center is 180°. Let the angle at the circumference be θ. The angle at the center is twice the angle at the circumference. 180° = 2 × θ θ = 180° … WebAnd so if we wanna look at this whole angle, the angle that intercepts the major arc A, B, C, is going to be 180 degrees plus 69 degrees. So we're going to have 180 degrees, plus 69 degrees which is equal to, what is that, 249, 249 degrees.
