3. →CA, →BD

Step-by-step explanation:

Angle

An angle is a figure formed by two rays having the same vertex. Angles can also be formed by the intersection of two planes. These angles are called dihedral angles. Angles have three types, namely acute, right, and obtuse. Two angles can be complementary when their measures sum up to 90° and supplementary when their measures sum up to 180°. Angles can be named using three points, with the vertex letter in the middle. It can also be named by only using the vertex letter. Another way of naming the angle is by writing a lowercase letter or number in the middle of the angle.

Examples

• ∠XYZ
• ∠Y
• ∠2

Line segment

A line segment is a part of a line that is enclosed by two distinct endpoints. A segment is named by its two endpoints.

Examples

• ¯WX
• ¯XY
• ¯YZ

Ray

A ray is a section of a line that has one endpoint and goes on infinitely in only one direction. A ray is named using its endpoint first, and then any other point on the ray.

Examples

• →XY
• →DE
• →JK
