Find the area of the right triangle △DEF with the points D (0, 0), E (1, 1), and F.

Question

m∠DEF = 60°.

A √3
B √6
C √2
D
√3
√2

*line in between answer D*

Answer 1

Since <DEF is 60° and DE = √2, EF=√6.

So, the area is (√2*√6)/2 = √3

Rather than all this

*line in between answer D*

stuff, you could have just written √3/√2
