Question

Given: ABCD is a parallelogram( A top left, B top right C Bottom right, D bottom left)
Line AC bisects angle A and C

Prove: ABCD is a rhombus

Answer 1

ok....

Statement
1. Line AC bisects angle A + C
2. angles A and C are equal
3. angles B and C are equal
4. Sides A B C D are equal
5. ABCD is a rhombus

Proof
1. given
2. definition of bisect
3. definition of a parrellegram
4. opposite sides of congruent angles are congruent
5. Definition of a rhombus - a parallelogram with 2 sets of congruent angles and all sides congruent

Answer 2

statement-------------Reason
ac bisects ab // cd-----------------given
ad = dc-----------------iso triangles

for a parallelgram ab = dc
and ad = bc,
so the quad is a rhombus

Answer 3

assertion-------------reason ac bisects
