Here you will learn what is the formula for the angle of intersection of two circles.<\/p>\n

Let’s begin –<\/p>\n

Angle of Intersection of Two Circles Formula<\/h2>\n

The angle between the tangents of two circles at the point of intersection of the two circles is called angle of intersection of two circles<\/strong>.<\/p>\n

If two circles are \\(S_1\\) = \\({x}^2 + {y}^2 + 2{g_1}x + 2{f_1}y + {c_1}\\) = 0 and \\(S_2\\) = \\({x}^2 + {y}^2 + 2{g_2}x + 2{f_2}y + {c_2}\\) = 0 and \\(\\theta\\) is the acute angle between them<\/p>\n

then cos\\(\\theta\\) = |\\(2{g_1}{g_2} + 2{f_1}{f_2} – {c_1} – {c_2}\\over {2\\sqrt{{g_1}^2 + {f_1}^2 -c_1}}{\\sqrt{{g_1}^2 + {f_1}^2 -c_1}}\\)|<\/p>\n

or cos\\(\\theta\\) = |\\({r_1}^2 + {r_2}^2 – d^2\\over {2r_1 r_2}\\)|<\/p><\/blockquote>\n

Here \\(r_1\\) and \\(r_2\\)<\/strong> are the radii of the circles and d is the distance between their centres.<\/p>\n

Note<\/strong> : If the angle of intersection of two circles is a right angle then such circles are called “Orthogonal Circles<\/a>“.<\/p>\n","protected":false},"excerpt":{"rendered":"
