Please provide the complete figure for the 4(d).

Answer 1

4(a):

Observe the figures,

In , .

In , .

Find whether the triangles are similar or not.

If two pairs of corresponding angles in a pair of triangles are congruent, then the two triangles are similar.

Here three pairs of angles in both triangles are same.

Thus, the pair of triangles are similar.

Answer 2

4(B):

Observe the figure:

By the tranverse property of parallel lines.

are same.

are same.

If two pairs of corresponding angles in a pair of triangles are congruent, then the two triangles are similar.

Thus in and , two pairs of angles are same.

Therefore,  and  are similar.

Answer 3

4(C):

Observe the figure:

are same.

is same in both  and .

If two pairs of corresponding angles in a pair of triangles are congruent, then the two triangles are similar.

Thus in    and , two pairs of angles are same.

Therefore,   and  are similar.
