Answer with explanation:
Two geometrical shapes are said to be congruent, if their corresponding sides as well as Corresponding Interior angles are equal.
Similarly, two triangle are said to be congruent,if the length of corresponding sides are equal as well as their corresponding interior angles are equal.
Out of four triangles given
→→Size of triangle 1 , is very small , as compared to triangles 2,3,and 4.
→→Triangle 2, Δ 3,and Δ 4 appears congruent to each other, as their corresponding side lengths and Corresponding interior angles appears to be equal.
The following option must be true among 4 congruent triangles
→→Option A, E, and F
