Question

Sita draws angle meausuring
160 degrees. She now divides this angle
into 2
equal parts. What
is the measure of each of the
smaller angle:
angle​

Answer 1

Answer:

80

Step-by-step explanation:

since 160divided by 2=80

Answer 2

Answer:

Three examples from our daily life are as follows:

1) Angle formed at the vertex of our elbow with the upper arm and the lower arm as the two rays. This angle will vary as per the position of our arm.

2) Angle formed between the two hands of the clock that are hinged at a point.

3) Angle formed between the two hands of a windmill. They are also hinged at a point, which is called the vertex of that angleSteps of constructions

Step I - With the help of protractor, draw ∠AOB=∠60

∘

Step II - Cut OA and OB at U and X, taking O as the center and any convenient radius.

Step II - With vertex X as centre, by using compass take more than half of arc UX and draw an arc.

Step III- With vertex U as centre , by using a compass with the same length cut the previous arc at V and extend it to point C.

Step IV - With point X as centre, by using a compass take more than half of arc WX and draw an arc.

Step V- With vertex W as centre, by using a compass with same length cut the previous arc at Z and extend it to point D

Step VI - With point W as centre, by using a compass take more than half of arc UW and draw an arc.

Step VII- With vertex U as centre, by using a compass with same length cut the previous arc at P and extend it to point E
