Question

Justify the congruence between each of the following pairs of triangle.​

Answer 1

Refer to the attachment for the labelling of the triangles.

In △ABC & △DEC,

∠C = ∠C [common angles → vertically opposite angles]

AC = CE [equal pair of sides]

BC = DC [equal pair of sides]

•°• △ABC ≅ △EDC (Single-Angle-Side congruence rule → SAS congruence rule.....the angle is included between the 2 equal sides).
