Question

please tell me the answer ​

Answer 1

Answer:

In ∆ABC, ∠A = 30° , ∠B = 40° and ∠C = 110° In ∆PQR, ∠P = 30° , ∠Q = 40° and ∠R = 110° A student says that ∆ABC ≅ ∆PQR by AAA congruence criterion. It is not justified because AAA is not a congruence criterion. Triangles with similar measures of angles can be similar triangles but not congruent.

Answer 2

Answer:

Solution:

Given that, in ∆ABC, ∠A = 30° , ∠B = 40° and ∠C = 110°

in ∆PQR, ∠P = 30° , ∠Q = 40° and ∠R = 110°

It is not justified because AAA is not a congruence criterion.

Triangles with similar measures of angles can be similar triangles but not congruent.

Two similar triangles can also have all equal angles but different lengths of sides, so one triangle could be an enlarged version of another triangle.

That is why the reason given by the student is not justified
