You could prove two triangles are congruent by measuring each side of both triangles, and all three angles of each triangle. If the lengths of the sides are the same, and so are the angles, then the triangles are congruent... if not, then the triangles are not congruent. If the triangles have the exact same size and shape then they are congruent.

yes it is
Regular polygons have congruent angles such as squares and equilateral triangles.
No. For example the triangles with sides {3, 4, 5} and {6, 8, 10} are similar but not congruent.
A square and rectangle both have congruent triangles in them.

Congruent Triangles have the same angles and side length measures
A tetrahedron has four equilateral triangles as sides
No. For example the triangles with sides {3, 4, 5} and {6, 8, 10} are similar but not congruent.
Triangles are congruent if they have the same size and shape, meaning their corresponding sides and angles are equal.
trueImproved Answer:-It is false because the triangles could be similar in shape but not in size
