Question

if triangle ABC is translated up 5 units and to the right three units, which of the following would be the new coordinates of point B?

Answer 1

1) Start at point B.
2) Go up 5.
3) Go to the right 3.
4) Write the coordinate of that new point. :)

Answer 2

a. (-3,0)
b. (-1,-2)
c. (-1,-8)
d. (-9,0)

Answer 3

Here is a picture which illustrates what I was taking about. I made them in geogebra, a great little program for geometry and algebra (it's free and works on all operating systems!) :)

Answer 4

yay I got it right ;) thank youuu!

Answer 5

if tiangle ABC is reflected through the y-axis which of the following would be the new coordinates of point B

Answer 6

triangle*

Answer 7

Pretend the Y axis (the one that goes up and down) is a mirror. Now where would the point B appear to end up if it were reflected in this mirror?

Answer 8

how do i calculate the surface area of a triangular prism?
