WebOne hundred eighty degrees. And 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. That's the arc measure of this major arc A, B, C.

WebFinding a Circle's Center. We can use this idea to find a circle's center: draw a right angle from anywhere on the circle's circumference, then draw the diameter where the two legs hit the circle; do that again but for a different diameter; Where the diameters cross is the center! Drawing a Circle From 2 Opposite Points WebWe know that the radius of a circle is always perpendicular to the chord of a circle and it acts as a perpendicular bisector. Therefore, AD = 1/2 × AB = 16/2 = 8. Therefore, AD = 8 cm. Example 2: In the given circle, O is the center with a radius of 5 inches. Find the length of the chord AB if the length of the perpendicular drawn from the ...

WebA circular arc is the arc of a circle between a pair of distinct points. If the two points are not directly opposite each other, one of these arcs, the minor arc, subtends an angle at the centre of the circle that is less than π radians (180 degrees); and the other arc, the major arc, subtends an angle greater than π radians. The arc of a circle is defined as the part …
