Question

measure in protector 45° , 30° ,60° , 90° , 150°​

Answer 1

Answer:

Step-by-step explanation:

375 is the right answer

Answer 2

steps of construction to made 45°

• draw an line segment
• made an semi circle on line segment
• from one point of semi circle made an arc on semi circle
• do same with another point of semi circle
• from an arc point made an arc on up side of semi circle
• do same with another arc point
• draw arc line to up two arc point
• that is 90 degree angle
• make an angle bisector of 90°

to make 30degree

• draw an line segment and draw semi circle on it
• from one right hand side point of semicircle
• draw an arc on semi circle
• draw an line on arc
• this is 60 degree angle
• make an angle bisector of 30 degree

for 60 degree i can make it just

for 90 degree i can also make it

to make 150 degree

• draw an line segment and make semi circle on it
• from left hand side of semi circle point draw an arc on semi circle
• draw an line from centre to arc
• this is 120 degree
• make an angle between 180 to 120

if you didnt know how to do angle bisector see that

• like an angle 60 degree
• there have two lines
• made an arc between two lines from there where the two lines joining
• from an one point of arc and from second point of arc made an another two arc
• made an line from joint two line to end
