- Review the geometry concepts covered in class before taking the quiz.
Practice Problems
- Identify the point that is not collinear with points A and B.
- Find the measure of the angle that is formed by the intersection of lines m and n.
- Classify the polygon with 6 sides.
Step-by-step solutions to the practice problems are provided below:
- To determine the point that is not collinear with points A and B, we need to check if the three points lie on the same line. If they do, then they are collinear; otherwise, they are not collinear. We can use the slope formula to determine if the three points are collinear. If the slope between any two pairs of points is the same, then the three points are collinear. Otherwise, they are not collinear.
- To find the measure of the angle that is formed by the intersection of lines m and n, we need to use the angle addition postulate. The angle addition postulate states that the measure of an angle formed by two intersecting lines is equal to the sum of the measures of the two adjacent angles. We can use a protractor to measure the angles and then add them together to find the measure of the angle formed by the intersection of lines m and n.
- To classify the polygon with 6 sides, we need to use the definition of a polygon. A polygon is a closed figure that is made up of three or more line segments. The number of sides of a polygon is equal to the number of line segments that make up the polygon. Since the polygon has 6 sides, it is a hexagon.
