Explanation:

1. Identify the Figures
In this section, students are required to identify the given figures correctly. They can refer to the textbook or their notes to recognize the shapes and their properties.

2. Naming Angles
In this section, students need to name the angles in the given figures. They should know the different types of angles, such as acute, obtuse, and right angles, and how to measure them using a protractor.

3. Identifying Lines and Line Segments
In this section, students need to identify the lines and line segments in the given figures. They should know the difference between a line and a line segment and how to measure their length.

4. Identifying Parallel and Intersecting Lines
In this section, students need to identify the parallel and intersecting lines in the given figures. They should know the definition of parallel lines and how to identify them by their properties. They should also know that intersecting lines meet at a point.

5. Identifying Right Angles
In this section, students need to identify the right angles in the given figures. They should know that a right angle measures 90 degrees and how to recognize it in a figure.

Note: Teachers can modify the exercise according to the level of their students and the topics covered in their curriculum.
