Question

Draw circle of radius 3cm and draw chord pq of length 4.2 cm draw tangent at point p and q without using centre​

Answer 1

The tangents at point p and q without using center of circle with radius 3cm and a chord pq of length 4.2cm is given below.

• Steps to follow:
• Draw a circle with radius 3cm.
• Mark any point P on the circle.
• With a scale of 4.2cm draw an arc and mark point Q.
• Join points P and Q.
• Draw another line from P and mark it R.
• Join the points Q and R.
• Now, we get a triangle PQR.
• Draw an angle congruent to PQR through point P with PQ as one of the arms of the angle.
• Repeat the same process at point Q.
• Now draw the line joining the arcs and point P.
• Now draw the line joining the arcs and point Q.
• Hence the required tangents at points P and Q.
