Playing with Constructions

Why are geometric constructions important in mathematics?

1. They are useful only in examinations.
2. They help create accurate figures and develop understanding of geometric concepts.
3. They replace calculations completely.
4. They are used only to draw circles.

Why should a compass be handled carefully during constructions?

1. To make drawings colourful
2. To ensure accurate constructions and avoid damaging the paper
3. To increase the size of the circle
4. To measure angles

What is an arc?

1. A straight line
2. A part of the boundary of a circle
3. The centre of a circle
4. The radius of a circle

Which mathematical skill is improved by geometric constructions?

1. Memorization only
2. Accuracy and logical reasoning
3. Singing
4. Painting

What is the first step in drawing a circle with a compass?

1. Draw the circle immediately.
2. Fix the compass at the chosen centre.
3. Measure an angle.
4. Draw a rectangle.

To construct a line segment of a given length, you need:

1. Compass only
2. Ruler only
3. Protractor only
4. Divider only

Which instrument helps compare or transfer distances without measuring them?

1. Protractor
2. Divider
3. Compass
4. Scale

What is the diameter of a circle with radius 6 cm?

1. 6 cm
2. 10 cm
3. 12 cm
4. 18 cm

Which of the following is necessary to draw a circle of radius 5 cm?

1. Only a ruler
2. Only a protractor
3. A compass and a ruler
4. A divider only

The distance from the centre of a circle to any point on the circle is called:

1. Diameter
2. Radius
3. Chord
4. Arc

The fixed point of a compass while drawing a circle is called the:

1. Diameter
2. Radius
3. Centre
4. Circumference

A ruler is mainly used to:

1. Draw circles
