Q:
# Please help(:Two planes intersect to ____ form a lineA. AlwaysB. SometimesC. Never.D. Inconclusive. Which of the following is true? A. All quadrilaterals are polygons with two pairs of parallel sides.B. All quadrilaterals are polygons with four sides.C. All quadrilaterals are polygons with at least one pair of parallel sides.D. All quadrilaterals are polygons with four sides at least one pair of parallel sides.

Accepted Solution

A:

Answer

Question 1. ALWAYS

Question 2. B. All quadrilaterals are polygons with four sides.

Explanations

Question 1:

When two planes meet they do so forming a line. This is to mean that the point of intersection is always a line.

Question 2:

It is not necessarily for a polygon to have a pair of parallel sides. A regular pentagon is polygon with no pair of parallel sides. So a quadrilateral is a polygon with four sides. The sides don’t have to parallel for it to be a quadrilateral. The correct answer is B.
