Question

To draw a pair of tangent to a circle which are at right angle to each other it is required to draw tangents at end points of the two radii of the circle which are inclined at an angle of_​

Answer 1

Answer:

Clearly from the figure, by joining radii to both the point of contact, we get quadrilateral & the sum of opposite anlges of a quadrilateral is 180°

Since, θ=90∘

Angle between the radii =180∘−90∘=90∘
