Question

construct a tangent segment of length root 21 cm to the circle of radius 2 cm with center P​

Answer 1

constructed a tangent segment of length √21 cm to the circle of radius 2 cm with center P​

Step-by-step explanation:

Radius PA = 2 cm

Tangent AB = √21 cm

PB² = PA² + AB² = 2² +(√21)² = 4 + 21 = 25

=> PB = 5 cm

Step 1 : Take a point P and draw  a circle with compass taking width = 2 cm and P as center

Step 2 : Mark any point A on circle

Step 3 : Join PA

Step 4 : Draw an angle of 90° at A on PA using setsquare/protector

Step 5 : Taking compass width = 5 cm & P as center draw arc such that it intersect angle drawn in Step 4 at B

AB is the required tangent of √21 cm
