Step by Step Solution
Step 1
For triangle I, there is no internal
angle that is 90°. Hence, this is not
a right triangle.
Step 2
As for triangle II,
the angle at vertex A is 90°.
Hence, this is a right triangle.
Step 3
Now,
as for triangle III, the 'square' below
represents the angle 90°. Hence, this
triangle is a right triangle.
Step 4
For triangle IV, there is no angle that
is 90°.
Hence, this
is not a right triangle.
Step 5
Clearly, only triangle II and III
are right triangles. Therefore, the answer
is B.
