please give 5 star rating

Answer 2

Answer:

1) we can se there are 6 angles

in triangle the 3 angles are equal to 180 so 6 angles will be

180+180=360

2)we can prove triangle abc and abd congurent to prove line bc and bd equal

ab=ab(comman)

<abc=<abd(given)

<cab=<bad(each 90°)

so, both triangle are equal

bc=bd (cpct)

so two sides are equal ,hence it is an isosceles triangle.
