How to construct 150 degree in lesson practical geometry class 8
Answers
Answer:
150,
is the right answer
Hey Mate ! This is your Solution:
These are the steps to draw :
1] Draw a line segment XOY .
2] With O as centre and any radius, draw a semi circle with cuts from both (end,start) point on XY.
3] Mark the intersection point as A and B .
4] With B as centre and same radius as before, Mark an arc at the semicircle. Mark this as C .
5] The angle COB is 60° .
6] Now, with C as centre and same radius, Mark an arc at between the angle AOC.
7] Now, with A as centre and same radius, Mark an arc and intersect it with the previous arc at D.
8] Angle BOD = 120°.
9] Now, With D as centre and same radius, Mark an arc somewhere between Angle AOD .
10] With A as Centre, and same radius , Mark an arc which cuts previous arc at E.
11] Angle EOB = 150°.
12] See the figure for clearer information :)
Note : Always remember, the radius if the arc should never be changed, or else the angle will be produced wrong.
Hence, Produced !
Don't Forget to mark as brainliest!
