Finding Unknown Measures in Congruent Figures
If two figures are congruent, then the measures of their corresponding parts are equal. If , then the lengths of corresponding sides are equal () and the measures of corresponding angles are equal (). Key formulas include expressions such as \triangle ABC \cong \triangle DEF. This concept is part of Big Ideas Math, Course 2, Accelerated for Grade 7 students, covered in Chapter 1: Transformations.
Key Concepts
If two figures are congruent, then the measures of their corresponding parts are equal. If $\triangle ABC \cong \triangle DEF$, then the lengths of corresponding sides are equal ($AB = DE$) and the measures of corresponding angles are equal ($m\angle A = m\angle D$).
