Question

all the question plzzz answer

Answer 1

Answer:

Step-by-step explanation:

Q1  radius is perpendicular to tangent at points of contact, so join both the radii to both points or tangents. let radius be r. 2r = d (diameter)

hence proved

Q2 bhai same chiz, radius is perpendicular to tangent at point of contact, so angle PQR = angle PRO = 90, PQR+PRO = 180, and using ASP of quadrilaterals, sum of other 2 angles is also 180. since opposite angles of quadrilateral are supplementary, it is a cyclic quadrilateral

aur bhai agar dhanka answer ya phir pura answer chahiye agli baar kuch accha points daal de
