Dear Student,


Steps of construction:
1) Draw a line segment AB=4 cm,
2) At A, construct angle BAX= 45$°$
3) With A as a centre and radius 4 cm, draw an arc that the ray AX at point D,
4) With B, as a centre and radius 2.8 cm , draw an arc AB.
5) With D as a centre and radius 2..5 cm , draw an arc that cuts the previous arc at C.
