Tricky maths

GILLI40 · #1 Nov 1, 2009, 02:49 AM

Can anyone help solve this mathematics question?
The question is as follows:

"the coordinates of the vertices o,a and b of a triangle are (0,0),(12,0) and
(0,16) respectively.
A)verify that the point with coordinates (4,4) is equidistant from the three sides of the triangle oab."

thank you.

One way of doing it is by plotting the points given, plus the point with coordinates (4, 4), then measure the distance.

The second way of doing it is finding the distance OX, then AX then BX, where I'm calling the point (4, 4) as X. The formula for distance is $d^2 = (x_2-x_1)^2 + (y_2-y_1)^2$
