Question

Which of these triangles appears not to be congruent to any others shown here?

Answer 1

Triangles A and E and C and F are congruent. Triangles B and D are not congruent.

Explanation:

We have given the figure of triangles.

We have to show that Which triangles appears not to be congruent.

Congruent triangles have equal sides and equal angles.

So, from the figure it is clear that the triangles A and E are congruent and triangles C and F are are congruent.

The triangles B and D are not congruent because they have different sides and angles.

Answer 2

Triangle B ⇒ answer B

Triangle D ⇒ answer D

Explanation:

Triangles be congruent if:

1) There sides are equal in length

2) There angles are equal in measures

From the figure:

Triangles A and E appears to be congruent

Triangles C and F appears to be congruent

Triangles B and D appears not to be congruent
