12 Consider the two triangles in the image shown below. James says the triangles are congruent by AAS. Which single additional assumption is needed to support his claim? A There is no single assumption to support James's claim. The triangles are not congruent. B Vertical angles are congruent. C The measures of the interior angles of a triangle sum to 180°. The centroid of a triangle divides each median into two parts, from vertex to centroid and centroid to midpoint, in a ratio of 2: 1.

Magnitude

A vector is an element with both direction and magnitude. A vector is represented using an arrow, where the arrow represents the direction of the vector and its length is represented using the magnitude. The set of vectors in space is known as vector space. The vectors can be added, subtracted, multiplied, and divided in a vector space. The image below shows a vector AB.
