Question

Draw $\angle POQ$ of measure ${75}^o$ and find its line of symmetry.

Answer 1

R.E.F image

a. Draw a line | and mark a point o on it.

b. place the pointer of the compasses at o and

draw an are of any radius which

intersects the l at A.

c.Take same radius, with center A.

cut the previous arc at B.

d. Join OB, then $\angle BOA=60$ Degree

e. Taking same radius, with centre B.

cut the previous arc at C.

f. Draw bisector of $\angle BOC$. The angle is of 90 degrees.

Mark it at D. Thus $\angle DOA=90$ Degree.

g. Draw OP bar as bisector of $\angle DOB$.

Thus $\angle POA=75$ degrees.
