@perl i already drew the picture and i did #1 i just dont understand the rest
so you did step 1,2,3,4
yes and then i answered #1
The distance from a point to a line is the length of the line segment which joins the point to the line and is perpendicular to the line.
so you measure distance from a point to a given line by drawing a perpendicular to the given line through the point
and then measuring that perpindicular line segment
wait ok so by measuring do you mean like with a ruler or do i measure it with the degrees thing?
i have no idea what you are talking about
what i described is the definition of the distance from a point to a line, geometrically
ok but in order to measure it what would i do? because i dont get what your saying... im not very good at this stuff
suppose you start with a point P and a line m
and you want to find the distance between P and line m
Is the distance between P and line m the length of this line segment? |dw:1432845743500:dw|
no, because the distance between a point P and line m is defined as the *shortest* distance between the point and the line.
and we can find the *shortest* distance by the following construction. draw a perpendicular to line m through P
lets call the point where the perpendicular line meets line m , call it T
now the distance between point P and line m is the length of PT
wait...im suppose to do this in a circle. so heres my drawing which lines would be p and m|dw:1432845934490:dw|
ok that makes more sence
to which m ? or am i connecting them with the perpendicular through P?
i think you should look at each one separately
remember in the steps, we set the compass from the center to each radius, and marked off a congruent distance
and we are folding a line that is perpindicular to the radius, so we can draw that right angle in
let's label the other chord a different letter, so we don't get confused
so it follows that the distance from P to chord n is `a`, and the distance from point P to chord m is `a`
so is that what i write for #2 or im so confused on how to measure the distance
website is extremely laggy for me
its ok i can email you if thats easier
ill send it through messages
thats what i meant haha
Yes, they want you to measure the distance from the center of the circle to the chord with a ruler. You should get the same distance for both chords. then they want you to measure the length of each chord. (they should be the same length) then you are supposed to guess that "if chords are the *same* distance from the center of a circle, then those chords will have the same length... i.e. be congruent"
