Vectors on trapeziums, Vectors on triangles, Vectors on rectangles and parallelograms**Geometric Vectors Part 1**

This video introduces Geometric Vectors, along with the magnitude, opposite vectors, congruent vectors, and resultants.

1. A vector is a quantity that has both magnitude and direction. (It looks like a directed line segment).

2. The length of a line segment is the magnitude. The direction indicates the direction of the vector.

3. A vector with its initial point at the origin is in standard position.

4. The direction of the vector is directed angle between the positive x-axis and the vector.

5. If both the initial point and the terminal point are at the origin, it is called a zero vector.

**Geometric Vectors with Application Problems**

In a rowing exercise, John was rowing directly across a river at the rate of 4 mph. The current was flowing at a rate of 3 mph. Use a ruler to draw each vector to scale and draw a vector to represent the path of the boat. Determine the magnitude of the resultant velocity of the boat by measuring the vector.

A ship leaving port sails for 25 miles in a direction 35° north of due east. Find the magnitude of the vertical and horizontal component.

A piling for a high-rise building is pushed by two bulldozers at exactly the same time. One bulldozer exert a force of 1550 pounds in a westerly direction. The other bulldozer pushes the piling with a force of 3050 pounds in a northerly direction.

a. Find the magnitude of the resultant force upon the piling, to the nearest pound.

b. What is the directions of the resultant force upon the piling, to the nearest pound.
