Question

Determine whether the conjecture is true or false. Give a counter example for any false conjecture. Given points R, S, and T. Conjecture: R, S, and T and coplanar

Answer 1

True

Explanation:

Three points define a plane.

If two or more of the points are coincident, the points define an infinite number of planes. In any event, there is at least one plane that will contain all three points.

Answer 2

b. True.

Explanation:

Choices for this question are

a. False; the points do not have to be in a straight line.

b. True.

c. False; the points do not have to form right angles.

d. False; one point may not be between the other two.

If R, S, and T are ponts, that menas they are in the same plane.

Remember that coplanar means "in the same plane". So, when points, segments or lines are coplanar, it means they are placed in the same plane.

For example, if you put three glasses on the surface of your table, you can side that the points marked by the bottom of each glass are coplanar, because the surface of the table is a plane, and all glasses are in the same one.

Therefore, the answwe is true.
