Basic Geometric Ideas I

Identify the geometric figure.

• Line

• Ray

• Line Segment

• Perpendicular line

Answer explanation

A line is a uni-dimensional shape that extends in both directions infinitely. A line segment is a part of the line. Line segments are the distance between two defined endpoints

Ray has an endpoint and the other part goes indefinite.

II. It is represented by P or any letter.

III. It has no length, width, or height.

IV. A line may pass through a point

• I

• II

• III

• IV

It starts from one point and extends in one direction indefinetely.

• Line

• Line segment

• Ray

• Parallel lines

Which of the following statement is correct?

I. Parallel lines and intersecting lines are similar having a point of intersection.

II. Intersecting lines are the two lines in which they intersect each other at any angle, whereas the perpendicular lines are the two lines, in which they intersect at an angle of 90 degrees

• I

• II

• Both I and II
