The INSCRIBED ANGLE THEOREM says that the measure of any inscribed angle is half the measure of its intercepted arc. Likewise, any intercepted arc is twice the measure of any inscribed angle whose sides pass through the endpoints of the arc. m∠ADB = 1 2 …A 180-degree angle is called a straight angle. Angles that are exactly 90 degrees are called right angles, while those that are between 0 and 90 degrees are called acute. Angles that are between 90 and 180 degrees are considered obtuse.1. Central Angle. A central angle is an angle formed by two radii with the vertex at the center of the circle. Central Angle = Intercepted Arc. In the diagram at the right, ∠AOB is a central angle with an intercepted minor arc from A to B. m∠AOB = 82º. In a circle, or congruent circles, congruent central angles have congruent arcs.To draw the maze on your canvas, add this code at the bottom of your script: JavaScript. drawMazeAndRectangle ( 425, 3 ); // { 425, 3 } is the position // of the blue rectangle on the canvas. currRectX and currRectY represent the position of the rectangle, and intervalVar is the variable for the timer, which we will create later.Jun 15, 2022 · Practice: Chords and Central Angle Arcs This page titled 6.12: Chords and Central Angle Arcs is shared under a CK-12 license and was authored, remixed, and/or curated by CK-12 Foundation via source content that was edited to the style and standards of the LibreTexts platform; a detailed edit history is available upon request.
