Answer 1

Chekc the length and draw it

Question 2

How to know for a fact which side to pick for inequality of perpendicular bisect or

Answer 2

Lick point not on line and test ti see if works, use algae riaz equation if needed

Use the algebraic method anyways to find the line so you can acc sketch

Question 3

How to work out lädt arg for circle

Answer 3

Draw daigram good

Now remember that angle made by two tangents firm same point is same, then subtract form pi/2

Question 4

How to find the LEAST value of mod z? All steps for perpendicular bisect or

Answer 4

This is just the least distance from origin, which is the per pedi chair bisector from origin to bisector
So find equation fi busector, and perpendicular, equate the, (Remmeber no c for perpendicualr ad through origin), find intersection

Now find mod of this point!!

Question 5

How to do half lines ?

Answer 5

Find the coordinate

Make that a CIRCLE because undefined

Draw the angle, itshalf line bevausesomethign underneath will be negative angkeich is not the swme wh

Question 6

Answer 6

Gradien is y = inverse tan angle

And goes through pint

Domain is greater than x value, as it CANT BE THE X VALUE,

Or less thsn if it’s negativ e
