I am weeks behind my work due to an illness, and I have no idea what I'm doing. Any help is appreciated. Thanks.
1. Given quadrilateral PQRS with vertices P (-2,3) Q (1,0) R (7,6) and S (0,5) prove that PQRS is a trapezoid.
2. Prove, using coordinate geometry, that the diagonals of isosceles trapezoid FISH with vertices F (2a, b) I (5a, b) S (7a,0) and H (0,0) are congruent
4. Given: Parallelogram ABCD
Line CE is perpendicular to Line AB
Line CF is perpendicular to Line AD
Prove: Triangle DCF ~ Triangle BCE
5. Given: Triangle ABC is isosceles with base Line AC
Line BD bisects angle ABC
Prove: Triangle ADB is congruent to Triangle CDB
6. Given: R is the midpoint of Line QS
QS bisects Line PT
Prove: Line PQ is congruent to Line TS
7. Given: Triangle BAT, line CBTD and Line AB are perpendicular to CD
Write an indirect proof to show that line AT is not perpendicular to Line CD
