By ASA or Angle side ange criteria we can say that ΔRST is congruent to ΔRSU or ΔRST ≅ ΔRSU
What are the congruent triangles?
Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
What is ASA congruency rule or criteria?
The ASA rule states that. If two angles and the included side of one triangle are equal to two angles and included side of another triangle, then the triangles are congruent.
According to the given question.
We have two triangles RTS and RUS.
Aslo, it is given that
m ∠TRS = m ∠URS
And m ∠TSR = m ∠USR
Now, In ΔRST and Δ RSU we have
m ∠TRS = m ∠URS (Given)
m ∠TSR = m ∠USR (Given)
And,
RS = RS ( Common side)
Therefore, by ASA or Angle side ange criteria we can say that ΔRST is congruent to ΔRSU or ΔRST ≅ ΔRSU.
Hence, we have proved that ΔRST ≅ ΔRSU by ASA criteria.
