Answer:
Please check the explanation.
Explanation:
6)
Given ΔMNO ≅ ΔPQR
As congruent parts of congruent triangle are congruent.
and also given
so
m∠N = m∠Q
2x+6 = 4x+12
4x-2x = 6-12
2x = -12
Divide both sides by 2
x = -6
Thus, the value of x = -6
Therefore, option 'A' is true.
7)
Given ΔABC ≅ ΔDEF
As congruent parts of congruent triangle are congruent.
and also given
so
AB = DE
4v+2 = 6v-4
6v-4v = 2+4
2v=6
Divide both sides by 2
v = 3
Thus, the value of v = 3
Therefore, option 'A' is true.
