In the diagram BE is parallel to CD.
(a) Complete the following statement: Triangle ABE is ________ to triangle ACD.
(b) AB = 5 cm, BC = 10 cm and AE = 8 cm. Find length of ED.
(c) Angle AEB = . Find size of the reflex angle at D.
Explanation
Here,
(a) BE is parallel to CD, which means it is a side splitter theorem.
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
