construction 14

Construction - 14 - To construct a right angled D ABC when hypotenuse AC = 4 cm and hypotenuse and one acute angle are given (1) Draw a straight line AC = 4cm. (2) Taking OC as diameter, draw a semi circle on AC. (3) At A, construct meeting the semicircle at ..

To construct a right angled D ABC when hypotenuse AC = 4 cm and hypotenuse and one acute angle are given (1) Draw a straight line AC = 4cm. (2) Taking OC as diameter, draw a semi circle on AC. (3) At A, construct meeting the semicircle at B. Join BC. (4) Then D ABC is the requir..

Construction - 2 - To bisect an angle , we are required to bisect (i) With B as centre and any suitable radius draw an arc to cut AB at D and BC at E respectively. (ii) Take any radius greater than of ED, not necessarily the previous radius. (iii) With this radius, taking points D and E a..
