Hello Tejal, Angle Bisector-  An angle bisector divides an angle into two congruent angles. Perpendicular Bisector- A perpendicular bisector can be defined as a line segment that intersects another line segment into two congruent segments and is perpendicular to that segment. It forms the angle of 90° at the intersection.

Commutative Property of Multiplication:Multiplication is commutative for integers. That is, for any two integers, p and q,p × q = q × pIt means changing the position of integers in multiplication does not affect the product.Example:For two integers, 9 and 7, their product,9 × 7 = 7 × 9 = 63For two integers, 5 and –7, their product, 5 × (–7) = (–7) × 5 = –35

Spring balance :  Spring balance is a device used for measuring the weight of an object. It has a spring attached to a hook. When we attach the hook to the weight, the spring extends and the pointer shows us the weight in Newtons. It is working under the principle ... Read More

Six's thermometer is a thermometer used to record the maximum-minimum temperatures of a given location within a given time period, for instance, 24 hours. It is used to measure the extremes of the temperature. It is also called a maximum-minimum thermometer. It was invented by British scientist James Six.

Most nonstick pans are coated with Teflon. The good news is that ingesting small flakes of nonstick coating is not dangerous. The material will most likely just pass through the body.Moreover, Nonstick pans use less amount of oil to cook food, so it is better and hence highly recommended.Read More

Given: ∆ABC ~ ∆LMN  and  $\frac{BC}{MN} \ =\ \frac{5}{4}$    ....(i) To find: We need to Construct ∆ABC and ∆LMN. Solution: Now, we know that:  Corresponding sides of similar triangles are proportional. So, $\frac{AB}{LM} \ =\ \frac{BC}{MN} \ =\ \frac{AC}{LN}$   ....(ii) From equation (i) ... Read More

Water freezes at 0 degrees Celsius. So at -2 degrees, water is nothing but an ice cube. We all know that ice cube is cold. So at that temperature water is cold.
