yes.

?? There is no verb in the conclusion! Added: Oh! "form", not "from". A convex set has the property that, if two points are in the then so is the line segment between them. Imagine a circle with center at the "removed" point and two points at the ends of a diameter.A 2. If a single point is removed from a plane, then the remaining points from a

convex set.

TheNo answer 3. There are at least 8 sets into which space can be separated by

four different planes'threecoordinate planes in a coordinate system divide space into 8 sets.

Yes.S 4. Two circles must intersect in a point.

Yes.S 5. Three angles lying in one plane may have a common side.

No! Look up the definition of "linear pair" and contrast it with "vertical angles".A 6. If the sides of two angles are two pairs of opposite rays then the angles form a

linear pair.

What about two right angles?A 7. A supplementary pair consist of an acute and an obtuse angle.

Okay- can be but dont have to be.S 8. If three points are coplanar then they must be collinear.

[qiote]N 9. A complementary pair is a supplementary pair.[/quote]

That contradicts the definition of "half plane" given here:A. 10. A half plane contains its edge.

half plane: Definition from Answers.com

What definition areyouusing?

Gud day! Here's another problem..i try to answer these question yet i have doubt of answer. Can anyone please check my work? Thank you so much
