45°problem I'll mark it as brainlist..

Answer 1

draw a circle of measurement is 360

lenth of chord 5cm draw  

contaning 45°angle  

then our consrution of circle is ready                                                                                                                2.Draw a circle of 360°

then

draw a chord 5cm

and contaning a 3degrees measurement

90                                                                                                                                            3.Draw a line AB, 5 cm long.

At the two ends -A and B construct angles of 60 deg and name them BAP and ABP. Bisect angles BAP and ABP to intersect at O. With O as the centre draw a circle with OA=OB as radius. You will have <AOB = 120 deg. The major segment has the angle the centre as 120 deg, while the minor segment will have the reflex angle AOB = 240 deg.

Answer 2

⚡⚡Hello friend ⚡⚡

⭕Draw a circle of 360°
