Question

∆ABC can be constructed with BC=5cm, ∠B=60°, ∠C=70° using the congruence *

Answer 1

in my opinion it c thank you

Answer 2

Given:

In ∆ABC, BC=5cm, ∠B=60°, ∠C=70°.

To find:

The congruence used in the given question.

Step-by-step explanation:

Step 1 of 1

When we prove two triangles congruent, and two angles are given, and the side between those two angles is also given, we use the congruence ASA i.e., ANGLE-SIDE-ANGLE PROPERTY.

In the question angle B and C are given and the side between them is given so it will follow the ASA rule of congruence.

The triangle that can be constructed is given below:

1. First draw a side of length 5cm.
2. Taking B as center draw an angle of 60 degrees and extend the line.
3. Now, taking C as center draw an angle of 70 degrees and extend the line.
4. The point where the two line intersects is the point A.
