Direction: Write T if the statement is TRUE and F if it is FALSE. 1. Every four-sided polygon is a quadrilateral. _2. A rhombus with one right angle is a square. 3. Every convex quadrilateral is a parallelogram. 4. A square has a diagonal that are congruent and perpendicular. 5. A parallelogram with four congruent sides is a square. 6. If in a quadrilateral ABCD, the angles A and D are right angles, and mL B and MLC non-congruent, then ABCD is a trapezoid. are 7. A rhombus with congruent diagonals is a rectangle, 8. The diagonals of a rectangle may be perpendicular. 9. If the bases of the trapezoid MADE are segments ME and AD, then the angles M A, and angles D and E are supplementary. and 10. The diagonals of a square may be non-congruent. 11. Angle bisector - two angles sharing a common side vertex but no interior points in common. 12. Vertical angles - angles formed by base and the legs. 13. Right angle - a line segment joining two non consecutive vertices of a polygon. 14. Diagonal - angle measure exactly 90 degrees. 15. Postulate - a statement that needs to be proven before being accepted. 16. Theorem a statement assumed to be true. 17. Base angle - two nonadjacent angles form by two intersecting lines. 18. Adjacent angle - line segment that divides the angles into two equal parts. 19. Opposite-"in front of" 20. Adjacent - "Next To"
