???????????????? maebee yu tri tu sae the 2 SHORT sides av triangel=
2 & 2*sqrt(5)
sqrt(5)=2.23606797749975
Tu get diagonal, 2^2=4, [2*sqrt(5)]^2=4*5=20
sum av squares=24
diagonal=sqrt(24)=4.898979485566356
????????????? wot trig funks du yu want ???????????
Maebee yu wanna get the ANGELS???????????
tu get angels, set base=sqrt(5) & hite=1
Then angel at base=invers tangent [1/root(5)]...tan(1/2.23606797749979)
=invers tan(0.4472135954999159)
=24.094842552108694 deg
1 angel=90 deg, other angel=90 -24.094842...
