Question

How would I find angle measures of a triangle given the points of the vertices?

Answer 1

FOR EXAMPLE:

triangle PQR has vertices P(1,5), Q(6,-7), and R(-2,1). how would i find the angle measures of this triangle

Answer 2

find the distance between the vertices using distance formula then use the law of cosines to find angle :o

Answer 3

@alexwee thank you ! lol i knew i had to use some formula... i used the slope formula... :S LOL idk why. i thought i'd get the measurement but nope haha. kk thanks again ! :)

Answer 4

k :D
