Short Review On Basic Geometry Terms

1) When lines are parallel how many times do they intersect?

None

Once

Twice

An infinite amount of times

When lines are parallel, they never intersect. This is because parallel lines are always equidistant and never converge or cross each other. Therefore, the correct answer is "none."

Explanation

When lines are parallel, they never intersect. This is because parallel lines are always equidistant and never converge or cross each other. Therefore, the correct answer is "none."

2) A line segment...

Goes on forever

Has two endpoints

Is the same as a line

None of the above

A line segment is a part of a line that is bounded by two distinct endpoints. Unlike a line, which extends infinitely in both directions, a line segment has a finite length and does not go on forever. Therefore, the correct answer is that a line segment has two endpoints.

A line segment is a part of a line that is bounded by two distinct endpoints. Unlike a line, which extends infinitely in both directions, a line segment has a finite length and does not go on forever. Therefore, the correct answer is that a line segment has two endpoints.

3) What it the degree of a straight line?

100

360

90

180

None of the above

The degree of a straight line is 180. In geometry, a straight line is defined as a line that extends infinitely in both directions and has no curvature. The sum of the interior angles of any straight line is always 180 degrees. Therefore, the correct answer is 180.

Explanation

The degree of a straight line is 180. In geometry, a straight line is defined as a line that extends infinitely in both directions and has no curvature. The sum of the interior angles of any straight line is always 180 degrees. Therefore, the correct answer is 180.

4) An obtuse angle is...

Between 0 and 90 degrees

Between 90 and 180 degrees

90 degrees

Between 180 and 360 degrees

An obtuse angle is a type of angle that measures greater than 90 degrees but less than 180 degrees. It is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees).

Explanation

An obtuse angle is a type of angle that measures greater than 90 degrees but less than 180 degrees. It is larger than a right angle (90 degrees) but smaller than a straight angle (180 degrees).

5) A point in a plane can have how many lines going through it?

One

None

Exactly two

Infinite amount

A point in a plane can have an infinite amount of lines going through it because any line can be drawn through a point in a plane. No matter which direction or angle the line is drawn, it will always pass through the point. Therefore, there is no limit to the number of lines that can pass through a single point in a plane.

Explanation

A point in a plane can have an infinite amount of lines going through it because any line can be drawn through a point in a plane. No matter which direction or angle the line is drawn, it will always pass through the point. Therefore, there is no limit to the number of lines that can pass through a single point in a plane.
