In which formula is .

So, Triangle ABE is **similar** to triangle ACD.

(b) AB = 5 cm, BC = 10 cm and AE = 8 cm.

Now,

Now as per side splitting formula:

(c) Angle = . So, size of the reflex angle at D is similar to angle because and so both triangles are similar.

So, size of reflex angle at D is
