AH¯¯¯¯¯ and BC¯¯¯¯¯

HI¯¯¯¯ and BC¯¯¯¯¯

EF¯¯¯¯¯ and HI¯¯¯¯

EF¯¯¯¯¯ and AI¯¯¯¯
Done

Answer 1

Do you have a figure?

Answer 2

yes but how to show do i cop and past it to this

Answer 3

if the image is on a webpage, right click it, save image as, save it somewhere
click on thiis website, click attach file, post the image

Answer 4

In a circle, all radii are congruent.

Answer 5

Also, in a circle, all diameters are congruent.

Answer 6

Look at all your choices.
If one choice has two radii, then they must be congruent.
If a choice has two diameters, then they must be congruent.

Answer 7

so its b

Answer 8

that would be incorrect
you are trying to compare a diameter
HI is the diameter as it touches the edges of the circle, but also passes throught he centre

Answer 9

however BC does not cross the centre

Answer 10

o right

Answer 11

ok so if they cross the center that's the answer

Answer 12

HI is a diameter.
BC is not a diameter.
HI and BC are not congruent.
Answer is not b.

Answer 13

not necessarily

if you find 2 lines that go from one side, through the centre to the other side then that would be the answer

however the circle also has radius
the radius starts at the centre and touches the edge of the circle

so if you find 2 lines that look like that, then that could also be the answer

Answer 14

for example
AD and AH are both a line that represent the radius, that means they are congruent as they are the same, therefore they are equal length

Answer 15

i think i got it c look like it crosses

Answer 16

well done :)

Answer 17

thanks man i fill a little way better i was probably over thinking it as always

Answer 18

There are 5 radii shown. They are all congruent to each other. Notice that none of the choices have two of the radii.
