Question

The coordinates A(2, 1), B(7, 1), C(2, 4) form a right triangle
True or False

Answer 1

Try drawing it please.

Answer 2

You will not learn anything if I draw it for you...

Answer 3

Do u have any grap paper?

Answer 4

If so... you draw GRAPH andplot the points and see for yourself

Answer 5

Alternative Way:

Find the slopes of the following segments: AB, BC, AC

Then multiply these slopes in pairs (slope of AB * slope of BC, slope of AB * slope of AC, slope of BC * slope of AC)

if any product is -1, then you have two perpendicular line segments

Answer 6

no it just asks me true or false with the question

Answer 7

When given points A(x,y) the first number goes on the x-axis and the second number on the y-axis.

Answer 8

for that to be a right angled triangle two of the lines must be parallel so we check that by multipling their gradients if the are their product must be -1

Answer 9

@ThreeOne "... two of the lines must be parallel .."
should be " two of the lines must be -parallel- perpendicular"

Answer 10

thanx skulpatrol I rily meant perpendicular

Answer 11

@autumnpoteet To answer true or false you should really try to get a visual picture of what it looks like, no?
