2020 Tri 2 Geometry B / Week 8 Unit 4: Coordinate Geometry / 4.2 Distance and Mi
4. The three points A, B and C make a triangle and have the coordinates
A(7, -8), B(6, -9), and C(13, -14). What type of triangle is it?
Scalene Obtuse

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
