Triangle middle crossbar

Calculate the length of the middle crossbars in an isosceles triangle if the length of the arm is 52 mm and the base height is 48 mm

Final Answer:

m1 =  20 mm
m2 =  26 mm
m3 =  26 mm

Step-by-step explanation:

r=52 mm h=48 mm  r2 = h2+(a/2)2  a=2 r2h2=2 522482=40 mm  m1=a/2=40/2=20 mm
m2=r/2=52/2=26 mm
m3=r/2=52/2=26 mm
