Question

Q1. Draw any angle with vertex 0. Take a point A on one of its
arms and B on another such that OA =OB. Draw the
perpendicular bisectors of OA and OB. Let them meet at P. Is
PA=PB?
Q2.Draw an angle of measure 145º and construct its bisector.
Q3.Construct the following angle measures with ruler and
compass:
(i) 45° (ii) 135°
(iii) 15°​

Answer 1

Step-by-step explanation:

2)Steps of construction: (a) Draw a ray OA. (b) With the help of protractor, construct ∠AOB = 147 degree. (c) Taking centre O and any convenient radius, draw an arc which intersects the arms OA bar and OB bar at P and Q respectively. (d) Taking P as centre and radius more than half of PQ, draw an arc. (e) Taking Q as centre and with the same radius, draw another arc which intersects the previous at R. (f) Join OR and produce it. Thus, OR bar is the required bisector of ∠AOB
