1. True. Diagonals in a rectangle are congruent.
2. False. Diagonals in a rectangle are NOT perpendicular.
3. False. In a rectangle, diagonals do NOT bisect angles.
4. True. Rectangle is a parallelogram, but parallelogram is not a rectangle.
5. True.
6. True. The diagonals in a square are perpendicular, which means the angles in the middle are right angles.
7. True.
8. False. The sum of the two angles are 90, given that angle J is also 90, since the sum of all angles in a triangle (triangle JFG) must be 180.
9. True. A diagonal divides a parallelogram into two congruent triangles.
10. True.
