Angles Formed by Intersecting Chords: Chords are line segments whose enpoints are on the circle. When these chords intersect, they form four angles and four intercepted arcs on the circle. For a pair of vertical angles, the measure is equal to half the sum of the measures...
First, we learned that the angle formed by two chords equals half the sum of the measures of the intercepted arcs. Next, we looked at the angle formed by a chord and a tangent line. This is half the measure of the arc the chord creates. Read Measurements of Angles Involving Tangents,...

130 Mathematics 19 Angles in a Circle and Cyclic Quadrilateral 19.1 INTRODUCTION You must have measured the angles between two straight lines, let us now study the angles made by arcs and chords in a circle and a cyclic quadrilateral. 19.2 OBJECTIVES After studying this lesson, the learner will...
A subtended angle is formed when two points (not necessarily the ends) on an arc are connected with a line segment that passes through their midpoint. It forms an angle between these two points which we refer to as a "subtended angle". Its measure can be calculated using simple ...

The painting was saved from further obscurity only as a consequence of the French Revolution, when it was moved to the newly formed Louvre Museum in 1797. For a few years Napoleon claimed theMona Lisaand hung it in his bedroom in the Tuileries, but in 1804 the Louvre reclaimed it and ins...
Different formulas are used, depending on whether the angle in question is formed inside or outside the circle's circumference. How can the measure of an arc angle on the circumference of a circle be found? The measure of an arc angle is found by dividing that arc length by the circle'...
