danni_joanaveil2 · Answer

so what kind of triangle would it be?

visarika23 · Answer

AB=sqr root(73)
BC=sqr roo1(73)
so it is an isoceles triangle

visarika23 · Answer

because two sides are equal

visarika23 · Answer

u know the distance formula, right??

danni_joanaveil2 · Answer

not really. is it A squared+B squared=C squared?

visarika23 · Answer

nooo
this is only in right angle triangle where sum of square of two sides = square of third side (longest side)
and this is called pythagoras theorem

danni_joanaveil2 · Answer

so like a hypotenuse?

visarika23 · Answer

yes c is hypotenuse

danni_joanaveil2 · Answer

thanks! that helped alot :)

aakashtomar · Answer

You can apply the pythagoras here too. Just draw a perpendicular from A on BC. Then you will have two right angled triangles.

visarika23 · Answer

Distance formula is
$$\sqrt{(x1-x2)^{2}+(y1-y1)^{2}}$$

visarika23 · Answer

sorry it will be y2

danni_joanaveil2 · Answer

really again thanks to both of you

visarika23 · Answer

ur wlcm:)

aakashtomar · Answer

Nah don't thank me she's done the question all by herself. :)

visarika23 · Answer
