Geometry math question no guessing and show work you

In an isosceles triangle , two sides are equal

so we check for option A and C

let us check for each,

option A:

1,1,3

sum of two sides > third side

but here 1+1<3

so this cannot be possible triangle

option C:

{6,6,5}

6+6 =12 >5

6+5=11>6

so it satisfies both the conditions, so option C {6,6,5} is correct

hey i’m new i won’t be answering any questions now bye peeps see you next time

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
