876 - 678 = 198
876 + 678 = 1554

198 < 3rd side < 1554
ttl = 1355

Angle PQT=90°
Angle TPQ=30°
So..
Angle QTP=60°
Triangle PQT is a 30-60-90 triangle....
So....
Side opposite to 30=1/2)hypo

PQ=PT/2
PT=2PQ
PT=TR+PR
TR+PR=2PQ
But PQ==PR
So TR=PQ=RQ
Tr:Rq=1:1

Bunny:
6 -2√5/2 = 3-√5 = r
4 -6+2√5
2√5 -2= s
s = 2[√5 -1]
Now for height
Triangle with sides 4 2√5 2√5
1/2*4*4 = R * [ 2+2√5]
R = 8/2+2√5 = 4/1+√5 = √5 -1
H = 2
1/2*2*2(√5-1)
= 2(√5-1) ans
