But 36 is not at the centre!? The Ryle is that angle at centre should be twice that of that on the circumference? :3

That's what i said. Angle at center is twice.

Acha khair hai. Look, you'll get the mirror right? So first draw the mirror line. Then drag one point to the mirror and note the distance/blocks that you've moved. Then from the mirror, drag the same point till the required distance you found before. Do the same for other points. The image should be laterally inverted. Got it?

I know this. I face problem with the direction in which to extend the lines.

b part :/

Protactor nikalo,measure karo,angle 18 k kareeb ata hai to 18 likhdo cuz its the only logical tukka by the angle given that is 36

Two lines from C and Two from Center so subtended angle.

so??

 

[M.Omar]

mainay bhee 36 nikala tha
answer is 18

Yeah answer is 18 coz (<at centre=2<s at circumference )it,s tht property ...simply look at the angles subtended by these 2 pts.trace it out and u will find tht

so you no have any logic?

 

[FLRNAB]

so??

See again. I added an image
Angle at Center is 36 so Angle at C will be 36/2 = 18

Kiaaa?

 

[Dark Destination]

Logic bata to raha hoon. The chord is the same. So angle at circumference is half of 36.. which is at center!

SIMPLE RULE. ANGLE AT CENTER is TWICE angle at circumference.

Look at the diagram. And trace the two angles to the chord.

What is the alternate segment theory (i dont know the exact wording, it is a rule in circles)?

 

[***1D***]

Alright. I did this freq. polygon. DO I leave it as it is or do I end it at 20? (And should I have started from origin?)

I think SO! ***amd***?

 

[asadalam]

Alright. I did this freq. polygon. DO I leave it as it is or do I end it at 20? (And should I have started from origin?)

Extend and end it at 20.For these polygons we have to start from the first class i.e 0 and end at the last i.e 20,if it were 16<t<18 at the end we would extend and stop it at 18.But do extend till the axis.

 

[FLRNAB]

What is this?

 

[asadalam]

What is this?

It means any equivalent constants e. 2x4=8.5x4=20 8/20 and 2/5 are the same .

For locus questions
Do we have to indicate on our diagrams tht whether this locus refers to locus given as 1(in exams) or 2(as also given in questions).I mean do we have to give a mark or arrow and write tht this specific locus is in response to the 1st condition or 2nd e.t.c
