Card 1Line Segment vs Line

Draw a line segment AB of length 6 cm. How is it different from a line?

Answer

Step 1: Use a ruler and mark point A at 0 cm. Step 2: Mark point B at 6 cm. Step 3: Draw a straight line between A and B. This is a line segment. A line segment has two endpoints (A and B) and a fixe…

Card 2Diameter and Radius

If the radius of a circle is 5 cm, what is its diameter?

Answer

We know: Diameter = 2 × Radius Step 1: Radius = 5 cm Step 2: Diameter = 2 × 5 = 10 cm Answer: The diameter is 10 cm.

Card 3Diameter and Radius

The diameter of a bicycle wheel is 14 cm. What is its radius?

Answer

We know: Radius = Diameter ÷ 2 Step 1: Diameter = 14 cm Step 2: Radius = 14 ÷ 2 = 7 cm Answer: The radius is 7 cm.

Card 4Chord and Diameter

A circle has a radius of 9 cm. What is the length of its longest chord?

Answer

The longest chord of a circle is its diameter. Step 1: Diameter = 2 × Radius Step 2: Diameter = 2 × 9 = 18 cm Answer: The longest chord is 18 cm.

Card 5Parallel Lines

Draw two parallel lines using a ruler. How do you know they won't meet?

Answer

Step 1: Use a ruler to draw a straight line. Step 2: Keep the ruler parallel and draw another line below it. Parallel lines never meet because the distance between them remains the same at every poin…

Card 6Intersecting Lines

Identify: Do the hands of a clock form intersecting lines? Why?

Answer

Yes, the hands of a clock form intersecting lines. Reason: Both hands start from the same center point (the center of the clock). Since they cross each other at that point, they are intersecting lines…

Card 7Midpoint of Line Segment

Can a line segment have more than one midpoint? Explain.

Answer

No, a line segment can have only one midpoint. Explanation: The midpoint is the point that divides the line segment into two equal parts. There is only one point that is exactly halfway between the tw…

Card 8Radius and Real-Life Context

If the diameter of a pizza is 16 cm, what is the distance from the center to the edge?

Answer

The distance from the center to the edge is the radius. Step 1: Radius = Diameter ÷ 2 Step 2: Radius = 16 ÷ 2 = 8 cm Answer: 8 cm.
