PRACTICAL MENSURATION

LINES AND ANGLES

LESSON 105

A Line is that which has length only.

A Straight Line is one that does not change its direction.

A Curved Line is one that continually changes its direction.

Parallel Lines are those that have the same direc

tion.

The difference in direction between two straight lines that meet in a common point is called an Angle.

When one straight line meets another straight line so as to form two equal angles, the lines are said to be Perpendicular to each other, and the angles thus formed are called Right Angles.

When an angle is less than a right angle it is called an Acute Angle.

ہے

When an angle is greater than a right angle it is called an Obtuse Angle.

1. Draw two straight lines so as to form one angle; two angles; four angles.

2. Draw two straight lines so as to form an acute angle; a right angle; an obtuse angle.

3. Draw two straight lines so as to form one right angle; two right angles; four right angles; one obtuse and one acute angle; two obtuse and two acute angles. 4. Will the size of an angle be increased by lengthening its sides?

5. If two straight lines are drawn from a point, one due east and the other due north, what kind of an angle do they form?

6. If two straight lines are drawn from a point, one due east and the other northwest, what kind of an angle do they form?

SURFACES AND PLANE FIGURES

LESSON 106

A Surface is that which has the dimensions length and breadth.

A Plane Surface is a level surface. When no part of a surface is plane, it is called a Curved Surface.

1. What kind of surface is the floor of your schoolroom? The ceiling? The walls? The blackboard?

2. What kind of surface is that of a ball? Of a slate pencil?

3. Name three objects having a surface like that of a ball. Three having a surface like a slate pencil. Three having a surface like the top of a table.

A Plane Figure is a plane surface bounded by straight or curved lines.
