Question

In the following figure, side QS is congruent to side SP, RPQ=50^o  and PSR=60⁰

Then among P,Q,R,S , which two angles are equal?

Comments

qsn is not completely correct.

QS is congruent to SP

do you want to say triangle QSP is congruent to triangle SPR?

  P=50^o  and S=60⁰

S=60⁰, what this means?.... RSP=60⁰  or QSP=60⁰ ?

What is meaning of congruent ?

congruent work with division , rt?

but in case of triangle how it works?

---

Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

Answer 1

Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.

So in triangle SPQ by property of triangle if two sides are equal then corrosponding opposite angle must be equal. i.e SQ= SP so,  $\angle$ SPQ = $\angle$ SQP
