Triangles: Q, R, S, T

Side 1: Q = 25, R = 26, S = 25, T = 25

Side 2: Q = 20, R = 20, S = 20, T = 26

Side 3: Q = 15, R = 26, S = 1,025, T = 650

**Kitralia Brown**, Friday, November 30, 2012 at 5:26pmNo, the triangles are named Q, R, S and T.. there are three sides to each of them; Side 1, Side 2 and Side 3.

But which one is a right triangle?

**Reiny**, Friday, November 30, 2012 at 6:01pmahh, so the triangles are grouped with sides:

25,20,15 and

26,20,26 and

25,20,1025 and

25,26,650

we can immediately rule out the last 2 groups since they don't even form any kind of triangle

So to be right-angled

a^2 + b^2 = c^2 , where c is the longest side, the hyppotenuse

is 20^2 + 15^2 = 25^2 ?

400 + 225 = 625 ? YES

is 26^2 + 20^2 = 26^2 , clearly NOT

so 20, 15 , and 25 will form a right-angled triangle.

**Kitralia Brown**, Friday, November 30, 2012 at 6:03pmAh, so it is Q! That is was I assumed, but I wasn't sure... I'm not too good at math. Thank you so much! :)
