Question

5. Let A, B be the centres of two circles of equal radii; draw them so that each on
of them passes through the centre of the other. Let them intersect at C and
Examine whether AB and CD are at right angles. ans plz​

Answer 1

Answer:

step 1 mark point A as a center

Step 2- since radius is 2.5 cm,

we measure 2.5 cm using ruler and compass

Step 3- Now keeping compass opened the same

length.

We keep pointed end at the center A,

and draw a circle using the pencil end of the

compass.

So, this is the left circle with center A.

Let AB be the radius.

Now, drawing circle of same radius with center

B.

Step 4- Now keeping compass opened the same

same lenght.

We keep pointed end at the center B,

and draw a circle using the pencil end of the

compass.

So, this is the right circle with center B.

Let them intersect at point C & D

joining C & D

Let X be point of intersection of AB & CD

On measuring the angles,

<AXC = <BXC = 90°

< AXD = < BXD = 90°

so, line segments AB & CD intersect at right

angles
