Help me!!!
it's simple look at the diagram tell how many triangles are present in it ?
3 but what about BE?
BD is not 4 ED is 4
OH i mean take ABC triangle lol
and find CA
how to find 3rd side while no angle is given?
why?
look at the angle DAB it's 90 and it's divided by two equal parts means 45 , 45 now the angle CAB must be 45 ...now find 3rd side
no DAB is not 90
yes it's 90 |dw:1446972863993:dw|
where did u get it? Not given in the question?
don't can you see it's 90
dont be silly you cant say an angle is look like 90 degrees just by looking at its type
but you can measure it from diagram ..so speak in good manners
i'm not trying to be rude english is not my main lanuage i dont believe it's 90 until a right explanation comes
okay they say that BD is bisector means divided the line into to two equal parts and as is bisector so it's perpendicular to the line CA right ?
you can say it's perpendicular only if ABC is isosceles triangle
