Finding lines tangent to a circle
WebAug 31, 2009 · A tangent line (PT) is always perpendicular to the radius of the circle that connects to the tangent point (T). It is therefore guaranteed to be a right triangle. The angles TOP and OPT will be different, but PTO will remain a right angle. Try it and see yourself! – John Feminella Jan 11, 2024 at 21:12 Add a comment 18

WebThe equation of a circle can be found using the centre and radius. The discriminant can determine the nature of intersections between two circles or a circle and a line to prove … WebIn the figure, chord 𝐴 𝐵 of the larger of the concentric circles is tangent to the smaller circle at 𝑋. Given that the radii of the circles are 26 cm and 16.1 cm, what is the length of 𝐴 𝐵 to the nearest tenth of a centimeter? Q6: Given that 𝐵 𝑁 = 1 1 c m , 𝐴 𝑀 = 2 1 c m , and 𝑁 𝑀 = 5 5 c m , find 𝐴 𝐵, rounded to the nearest hundredth. Q7:
WebLines A line that "just touches" the circle as it passes by is called a Tangent. A line that cuts the circle at two points is called a Secant. A line segment that goes from one point to another on the circle's circumference is called a Chord. If it passes through the center it is called a Diameter. And a part of the circumference is called an Arc.
WebCalculate the length of the tangent in the circle shown below. Solution DC 2 = 27 (10 + 27) = 27 *37 DC 2 = 999 Ignoring the negative value, we have DC = 31.61 Therefore, the of the tangent is 31.61 cm Example 6 Find the length of line XY in the diagram below.
