Question

.) Draw a pair of tangents to a circle of radius 4cm which are inclined to each other
at an angle of 90​

Answer 1

Step-by-step explanation:

# Step 1 : Draw a circle of radius 4 cm and centre O.

# Step 2 : Take a point A on the circle. Join OA.

# Step 3 : Draw a perpendicular to OA at A.

# Step 4 : Draw a radius OB, making an angle of 135° (180° – 45°) with OA.

# Step 5 : Draw a perpendicular to OB at point B.

Let these perpendiculars intersect at P.

# PA and PB are the required tangents inclined at angle of 45
