Vertical angles, QuickChek answers seventh grade

Answer 1

Vertical angles are formed when two lines intersect. They are the pairs of opposite angles that are across from each other.

Here are the QuickChek answers for seventh grade on vertical angles:

1. When two lines intersect, how many pairs of vertical angles are formed?
- The answer is 2. When two lines intersect, they form four angles. Each pair of opposite angles is considered vertical angles.

2. Are vertical angles congruent?
- Yes, vertical angles are always congruent. This means that they have equal measures.

3. Can vertical angles be supplementary?
- No, vertical angles cannot be supplementary. Supplementary angles are two angles that add up to 180 degrees, but vertical angles only have the property of being congruent.

4. How are vertical angles useful in geometry?
- Vertical angles help establish relationships between angles and lines in a geometric figure. They can be used in proofs and to find missing angle measures.

5. Can vertical angles be adjacent?
- No, vertical angles cannot be adjacent. Adjacent angles are angles that share a common vertex and side, but vertical angles are always opposite to each other.

Remember, these answers may vary depending on the specific curriculum or textbook being used.
