1. Each two alternate angles are ........ in measure.

Alternate angles are a pair of angles formed when a transversal intersects two parallel lines. These angles are located on opposite sides of the transversal and are congruent, meaning they have the same measure. Therefore, each pair of alternate angles is equal in measure. The symbol "=" is used to represent equality, indicating that the measure of each alternate angle is the same.

Explanation

Alternate angles are a pair of angles formed when a transversal intersects two parallel lines. These angles are located on opposite sides of the transversal and are congruent, meaning they have the same measure. Therefore, each pair of alternate angles is equal in measure. The symbol "=" is used to represent equality, indicating that the measure of each alternate angle is the same.

2. The Sum of two supplements angles = 90 degrees

True

False

The Sum=180

Explanation

The Sum=180

3. Each ......... angles are equal in measure.

Interior

Supplement

Corresponding

Adjacent

Corresponding angles are formed when a transversal intersects two parallel lines. These angles are located on the same side of the transversal and in the same relative position with respect to the parallel lines. Corresponding angles are always equal in measure, making them congruent. Therefore, the given statement that "corresponding angles are equal in measure" is correct.

Explanation

Corresponding angles are formed when a transversal intersects two parallel lines. These angles are located on the same side of the transversal and in the same relative position with respect to the parallel lines. Corresponding angles are always equal in measure, making them congruent. Therefore, the given statement that "corresponding angles are equal in measure" is correct.

4. The sum measures of the accumulative angles at a point is …….°.

90

180

360

120

The sum of the accumulative angles at a point is always 360 degrees. This is because a point is considered to be the intersection of two lines, and the sum of the angles formed by these lines is always 180 degrees. Since there are two lines intersecting at a point, the total sum of the angles at that point is 180 degrees + 180 degrees = 360 degrees.

8. For the following numbers 2, 5,1,9,2,4,7,17,0

The Mode= 2

The mean= 12

The median=4

The mode is the value that appears most frequently in a set of numbers. In this case, the number 2 appears twice, which is more than any other number in the set. Therefore, the mode is 2. The median is the middle value when the numbers are arranged in ascending order. The set of numbers arranged in ascending order is 0, 1, 2, 2, 4, 5, 7, 9, 17. The middle value is 4, so the median is 4.
