Question

Draw a circle of radius 2.5cm . Construct a pair of tangents to this circle which are inclined to each other at an angle of 30°

Answer 1

Answer:

Step-by-step explanation:

◆ Draw a circle with r 2.5

◆ Draw a radius OA

◆ Draw 90° on A and extent the line

◆ Draw 150 ° on O with compass or protractor

◆ Extent that line and let it touch the circle at B

◆ Now draw a 90° on B and extent the line

◆ The line extended from A and B meet at C which is 30°

Here we take 150 ° in the middle because 180 -30=150 { opposite angles of a quadrilateral are supplementary}

Answer 2

Hope this helps...

In the figure OA and OB are radius and so OA=OB=2.5 cm
