RHS

iv.

SAS​

Answer 1

Answer:

The major topics covered in congruent triangles class 7 are:

Congruence of Triangles

Congruence of Plane Figure

Congruence among Line Segment

Congruence of Angles

Criteria for Congruence of Triangles

Congruence among Right Angled Triangles

Answer 2

Answer:

Here, AB = EF ( = 7 cm)

BC = DE ( = 5 cm)

included ∠B = included ∠E ( = 50°).

A ↔ F

B ↔ E

C ↔ D.

Therefore, ∆ABC ≅∆FED

(By SAS congruence rule)
