Plzz solve 3,4,5,6...URGENT
Dear Student,
Solutions for the questions are as under:
Answer (3):
In the given figure, we can see that;
Hence, considering
Thus, based on SAS (Side Angle Side) property we can say that are congruent with each other.
Therefore, BC = DE (the third side of the congruent triangles)
Answer (4):
It is given in the question that are congruent with each other. Thus, the corresponding sides which are equal with each other as per the properties of congruency, will be;
But will not be equal to , as these are not the corresponding sides. Thus it is false to say that .
Answer (5):
It is given in the question that are congruent with each other. Thus, the corresponding sides which are equal with each other as per the properties of congruency, will be;
Hence, we can definitely say that will be equal to , as these are the corresponding sides. Thus it is true to say that .
Answer (6):
It is given in the question that angles A, B and C of the triangle are equal with each other. Hence we can also say that all the three angles are congruent with each other.
Thus,
Now, in a triangle, sides opposite to the equal and congruent angles are always equal with each other.
Hence,
Therefore, we can that .
Since, in , all the angles are equal and all the sides are equal, thus is an equilateral triangle.
Hope this information will clear your doubts about the topic.
