1.if the plane xoz divides the join of ( 1,-1,5 ) and ( 2,3,4 ) in the ratio λ : 1, then λ = a. -3 b. -1/3 c. 3 d. 1/3
2.the ratio in which the join of ( 1,-2,3 ) and ( 4,2,-1 ) is divided by xoy plane is
a. 1: 3
b. 3: 1
c. -1: 3
d. 1: -3
3.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
