Congruent Shapes Flashcards

Shapes that are identical in size and shape. They have the same angles and side lengths.

Two shapes are congruent if they can be mapped onto each other using a combination of transformations: reflection, rotation, or translation.

Two triangles are congruent if all three sides of one triangle are equal to the corresponding sides of the other triangle.

Two triangles are congruent if two sides and the included angle of one triangle are equal to the corresponding sides and angle of the other triangle.

Two triangles are congruent if two angles and the included side of one triangle are equal to the corresponding angles and side of the other triangle.

Two right-angled triangles are congruent if the hypotenuse and one other side of one triangle are equal to the corresponding parts of the other triangle.

Congruent shapes can be mapped onto each other using transformations such as reflection, rotation, or translation.

Congruent shapes are identical in size and shape, while similar shapes have the same shape but different sizes (proportional).

To prove two shapes are congruent, use one of the congruence rules (SSS, SAS, ASA, RHS) and show all corresponding parts are equal.

Two identical jigsaw puzzle pieces are congruent because they are the same size and shape.
