Question

by using ruler and compass draw a pair of tangents to a circle of radius 3.5 CM which are inclined to each other at an angle of 90 degree​

Answer 1

Step-by-step explanation:

this is the answer of angle 90 degress

Answer 2

Two perpendicular tangent as shown in the figure.

Step-by-step explanation:

Given,

Draw a pair of tangents to a circle of radius $3.5\ cm$ which are inclined to each other at an angle of $90\ degree$

Following steps:

• Take $O$ as center and $3.5\ cm$ radius, draw a circle.
• Draw two different radius which is $90\ degree$ to each other and intersect the circle at $A\ and\ B$  
• Draw perpendicular line with $OA$ at point $A$ like $AC\perp OA$ using compass.
• And $B$, draw perpendicular line with $OB$ like $BD\perp OB$using compass as shown in the figure.
• Where $AC$ intersect the line $BD$ at $E$ $AE\perp BE$

Hence, Two perpendicular tangent as shown in the figure.
