Question

How do you find the area of an acute triangle when you're only given the side lengths????

Answer 1

one way is; you can use the law of cosines to find an angle and use that angle in the side*side*sin(angle)/2 formula

Answer 2

the other is to use herons formula

Answer 3

so the area = \[a timesb \times \sin \] of the angle contained between a and b?

Answer 4

then, divided by two

Answer 5

thats right; so if you can find the angle between two sides, you can find the area

Answer 6

okay! Thanks :)

Answer 7

in my picture; base = b; height = a sin(angle) which fits into the normal

Area = b*h/2 that you are familiar with
