IGCSE Grade 10 Maths Angles forming chords secants and tangents
Two secants intersect in the exterior of a circle, then the measure of the angle formed is one-half the difference between the measures of the intercepted arcs.
If two secants intersect in the interior of a circle, then the measure of the angle formed is one-half the sum of the measure of the arcs (facing the angle) formed by the secants.
When a tangent and a chord meet at a point on a circle, the measure of each angle formed is half the measure of its intercepted arc.
∠BCD=(arc AE−arc BD)/2
the complete circle is 360\\(^{\\circ}\\)
• If two secants intersect in the interior of a circle, then the measure of the angle formed is one-half the sum of the measure of the arcs intercepted by the secant.
The angle formed by two secants outside the circle is half the difference of the measure of the intercepted arcs.
only a single line can pass through any two given points.
straight line angle is \\(180^{\\circ}\\)
A complete circle is \\(360^{\\circ}\\)
A complete circle is \\(360^{\\circ}\\).
