1. A triangle has __________ vertices.
a) one
b) two
c) three
d) four
View Answer
Explanation: As shown in below diagram, triangle ABC has three vertices namely A, B and C. Similarly, it has three edges AB, BC and AC and three angles ∠A, ∠B and ∠C.
2. Which one is true if triangle ABC is congruent to triangle PQR?
a) AB = PQ
b) AB = QR
c) BC = PR
d) ∠A = ∠Q
View Answer
Explanation: ABC \(\leftrightarrow\) PQR means triangles ABC and PQR are congruent to each other and if they are congruent to each other, AB = PQ, BC = QR and AC = PR.
Similarly ∠A = ∠P, ∠B = ∠Q and ∠C = ∠R.
And for vertices, A = P, B = Q and C = R.
3. From the diagram given below, which is true for two triangles?
a) Triangle ABC is congruent to triangle PQR
b) Triangle ABC is congruent to triangle QPR
c) Triangle ABC is congruent to triangle QRP
d) Triangle ABC is congruent to triangle RPQ
View Answer
Explanation: As we can see from the diagram that AB \(\leftrightarrow\) QR, BC \(\leftrightarrow\) RP and CA \(\leftrightarrow\) PQ.
Therefore we can say that triangle ABC is congruent to triangle PQR.
