Question

Draw a line segment of 8cm and draw its axis of symmetry
OR
Draw a angle of 60 degree and bisec it​

Answer 1

Answer:

Let's first draw a line segment of length .

1. Draw a line , mark point on it.

2. Since length is , we measure using ruler and compass.

3. Now keeping compass opened the same length, we keep pointed end at point A and draw an arc on line l.

So, the required line segment is .

Now, we need to find its axis of symmetry.

1. Given a line segment .

2. Now with as center, and radius more than half , draw an arc on top and bottom of .

3. Now with as center, and same radius, draw an arc on top and bottom of .

4. Where the two arcs intersect above is point and where the two arcs intersect below is point .

Join .

is the line of symmetry of line segment AB.

Answer 2

Answer:

Heat is the form of energy that is transferred between systems or objects with different temperatures (flowing from the high-temperature system to the low-temperature system). Also referred to as heat energy or thermal energy. Heat is typically measured in Btu, calories or joules
