Question

please give me answer this subject is math ​

Answer 1

Two triangles are congruent if their corresponding sides are equal in length, and their corresponding angles are equal in measure.

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

b) you'll have to do it with a scale using measurements
