Question:
Draw a circle of radius 2.6 cm. Draw any two of its diametres. Name the figure obtained
if we join the end points of the diameter
Solution:
Let us draw a circle of radius 5 cm
We follow these steps
- 1. Mark point O as center.
- 2. Let us make a circle of radius 5 cm,
we measure 5 cm using ruler and compass.
- 3. Now keeping compass opened the same length.
We keep pointed end at the center, and draw a circle using the pencil end of the compass.
So, this the circle with center O
and radius OP = 5 cm
Now, our question is
Draw a circle and any two of its diameters. If you join the ends of these diameters, what is the figure obtained? What figure is obtained if the diameters are perpendicular to each other? How do you check your answer?
Let us draw two diameters AB & CD
Joining ends of diameter
On measuring, AD = BC = 4.3 cm
AC = BD = 2.5 cm
& LA = LB =AngleC=AngleD= 90°
So, ABCD is a rectangle
Taking diameters perpendicular to each other
Let us draw two perpendicular diameters AB & CD Joining ends of diameter
On measuring,
- AD = BC = AC = BD = 3.53 cm
- & LA = ZB = LC= ZD = 90°
- So, all sides are equal and all angles are 90° : ABCD is a square
