Properties • SPECIAL PARALLELOGRAMS • RHOMBUS : • Diagonals are perpendicular. • Diagonals bisect the angles. • RECTANGLE : • Diagonals are congruent. • SQUARE : • has all the properties of rhombuses and rectangles
Exercises No. Even if the diagonals are perpendicular, the sides are not congruent.
Exercises Yes. Triangles are congruent By SAS. Therefore, opposite sides are congruent.
Exercises Determine the specific type of quadrilateral, and then solve for the variables.
