Question

3. Which pair of triangles can be proved congruent by SAS?

Answer 1

Answer: (3) The correction option is 2. (4) The correct option is 3.

Explanation:

(3)

The congruent rule SAS states that the two triangles are congruent if the two side and its inclined angle are equal to the corresponding sides and angle of other triangle.

In option 2 the base line contains the two equal parts. A line is perpendicular to the baseline, it means it makes 90 degree angle on both sides. The perpendicular line is common in both triangles.

So, only the option second represents the pair of triangles which are congruent by SAS.

(4)

The congruent rule SSS states that the two triangles are congruent if the three sides are equal to the corresponding sides of other triangle.

In option 3, it is given that the two side of both triangle are same to the corresponding sides of the triangle. The third side is common in both triangles.

So, only option third represents the pair of triangles which are congruent by SSS.

Answer 2

I just got this question and the answer is B. You're welcome.
