ack and Marianne are  trying to determine the sum of the interior angles for the polygon shown below.   Jack says that in order to determine the sum of the interior angles of the polygon you have to figure out how many triangles the shape can be cut into by drawing diagonals from one vertex to all other possible vertices..  Then you multiply the number of triangles by 180^o180o.   Marianne says that in order to determine the sum of the interior angles of the polygon you have to subtract 2 from the number of vertices and then multiply that number by 180^o180o

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
