Use similar triangles to calculate the height, h cm, of triangle ABE.


Use Similar Triangles To Calculate The Height H Cm Of Triangle ABE class=

Sagot :

Answer:

h=24cm

Step-by-step explanation:

∠DBC=∠ABE (vertically opposite angles)

∠CDB=∠AEB (alternate angles)

∠DCB=∠BAE (alternate angles)

Therefore the triangles DBC and ABE are similar.

That means that the triangles are in ratio to each other.

CD:AE

10:20

1:2

This means that the height of DBC is half the height of BAE.

Since the sum of their heights is 36, h is 2/3 of 36.

The height , h of the traingle is 24 cm.

What are Similar Triangles ?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

In other words, similar triangles are the same shape, but not necessarily the same size.

In the question , from the figure it is clear that

ΔDBC and  ΔABE are similar with AAA Similarity as

∠DBC=∠ABE (vertically opposite angles)

∠CDB=∠AEB (alternate angles)

∠DCB=∠BAE (alternate angles)

According to the theorem if the triangles are similar their sides are in ratio to each other.

CD : AE = 10 : 20 = 1 : 2

This means that the height of DBC =  half the height of ABE.

h+h' = 36

h+h/2 = 36

h= 24 cm

Therefore height of ΔABE is 24 cm .
