Question

an __ is a set of points consisting of two different rays that have the same endpoint, called the . the rays are the of the angle. you can name an angle in several different ways. the symbol ∠ represents an angle. • use its vertex, such as ∠a. • use a point on each ray and the vertex, such as ∠bac or ∠cab. make sure the vertex is the middle - letter. • use a number, such as ∠1. the region that contains all the points between the sides of the angle is the . the region that contains all the points outside the angle is the __. example naming angles name three angles shown in the diagram. solution

Explanation:

An angle is formed by two rays with the same endpoint (vertex), and the rays are its sides. The region between the sides is the interior, and the region outside is the exterior. For naming angles, we can use the vertex, points on the rays and the vertex (with vertex as middle - letter), or a number. In the given example, three angles with vertex \(X\) can be named as \(\angle WXV\), \(\angle VXU\), \(\angle WXU\).

Answer:

An angle is a set of points consisting of two different rays that have the same endpoint, called the vertex. The rays are the sides of the angle. The region that contains all the points between the sides of the angle is the interior. The region that contains all the points outside the angle is the exterior. Three angles in the example diagram can be named as \(\angle WXV\), \(\angle VXU\), \(\angle WXU\).
