Question

7. Measurements of some parts of two triangles are given:
<D=60°,< F = 80°,DF = 5 cm and <Q =60°,<R = 80°,QR=5 cm
Examine whether the two triangles are congruent or not, by which congruence rule. Write it
in a symbolic form in case of congruence.​

Answer 1

Answer:

I don't known about this question

sorry

Answer 2

Given triangle DEF

and triangle PQR

congruency means out of 6 measurements that is 3 angles and 3 sides if any 3 measurements are equal the two triangles are known to be congruent it may be side,side,side (or) Side, angle ,side(or) angle side angle(or) angle,angle,angle.

In the given question the two triangles consist 2 equal angles and 1 equal side and therefore triangleDEF is congruent to trianglePQR by ASA congruency.

SUGGESTION: whoever is reading this try to understand and write do not copy blindly or else you will not be able to do well ok!

ALL THE BEST!!
