Question

Draw a circle with centre O and radius 4cm.Draw tangents PA and PB to circle from point P outside of circle at point A and B respectively when angle APB is equal to 80 degree.

Answer 1

Given Angle p isb80°

•°• Angle O must be 100° because we know tangents make 90° with radius so the all angles sum must be 360°

So we can construct this by using protractor We can also do by using compass but it come complicated and elongated✓
