Question

if three angles in one triangle are congruent to three angles in another triangle,then the two triangles are congruent.true or false,if it is false make a counterexample

Answer 1

False

Because, two triangles are congruent if they will have exactly the same three sides and exactly the same three angles, in our case the three sides of first triangle are not given equal to the three sides of second triangle.

Counterexample : Three angles in one triangle are congruent to three angles in another triangle but all the sides of the second triangle are larger than the first triangle ,this case can be possible . And in that case we call these triangles similar triangles and not congruent triangles.
