24. Square
A square is a quadrilateral with four right angles & four congruent sides
All squares are parallelograms

25. Square

26. Square
A square is a quadrilateral with four right angles & four congruent sides
All squares are rhombuses, so diagonals create four congruent triangles

27. Square
A square is a quadrilateral with four right angles & four congruent sides
All squares are rhombuses, so each diagonal bisects two opposite angles

28. Square
A square is a quadrilateral with four right angles & four congruent sides
Diagonals create four congruent 45°-45°-90° triangles
