Question

construct an angle of 22 1 / 2

Answer 1

you can draw an angle of 22.5 degree buy bisecting an angle of 45 degree which is made by bisecting an angle of 90 degree

Answer 2

Now,the required angle '22.5' degree is angle BAC

Step-by-step explanation:

Given;

construct an angle of  $22\frac{1}{2}$

$22\frac{1}{2}=\frac{45}{2}$

Following steps;

• Draw a line  $AB$
• Draw an angle  $\angle BAE=45$
• With 'A' is a centre and small radious ,draw an acr cutting on  'AB' at 'P' and 'AE' at 'Q            
• With 'P' as a centre and a radious more than half of 'PQ' draw an arc  
• With 'Q' as a centre and a radious more than half of 'PQ' draw an another arc cutting the previously draw arc at   'D'
• Join 'A' and 'D'

Now,the required angle '22.5' degree is angle BAC
