Question 2.) => since all sides are equal, so SSS is the answer for Q-2
Question 3.) => Two angles and one side, so AAS is the answer for Q-3
4 x
5 20
80/5=16
20(total questions)/5(total questions, simplified)=4
Multiply 4 by 4(correct questions).
The second method is better for a student in elementary!
