Question

triangle ABC is congruent to triangle PQR if BC = 4 cm angle B = 60 degree and angle C = 70 degre then which of the following is true

QR=4 cm, angle P = 60
PQ= 4 cm, angle Q = 60
QR=4cm,angle R=60
QR=4cm,angleQ=60​

Answer 1

Answer:

4th option

QR=4CM and angleQ=60°

Answer 2

Given:

Triangle ABC is congruent to triangle PQR. BC= 4cm, angle B= 60degree and angle C= 70degree.

To find:

The correct option.

Solution:

As triangle ABC is congruent to triangle PQR, this means, the corresponding sides and corresponding angles of both triangles are equal.

So,

BC= QR, angle B= angle Q and angle C= angle R.

Hence,

BC= 4cm= QR

angle B= 60degree= angle Q

angle C= 70degree= angle R.

So, the correct option is: QR=4cm, angle Q=60.
