Which group contains triangles that are all similar A B C DS

Which group contains triangles that are all similar?

A.

B.

C.

D.

Solution

Solution:

Option (A) is correct

Explaination:

As we can see that in all three triangle all one angle is common and one angle is 90 in each

therefore reamining angle in each = 180 -90- common angle = 90 - common angle

therefore these triangle are similer to each other by AAA similer condition
