Question

question 1 (1 point) name an angle or angle pair that satisfies each condition. name two obtuse vertical angles. a ∠gfh, ∠cba b ∠bcd, ∠gcf c ∠gfh, ∠cfe d ∠gfc, ∠che

Explanation:

Step1: Recall vertical - angle definition

Vertical angles are formed when two lines intersect. They are opposite each other and are congruent. An obtuse angle is an angle with a measure greater than 90° and less than 180°.

Step2: Analyze the given angles

In the figure, when we look at the intersection of lines, we find that ∠GFH and ∠CFE are vertical angles. Also, we can observe that they are obtuse. For example, if we consider the relationships between the given 50 - degree angles and right - angles in the figure, we can determine that ∠GFH and ∠CFE are greater than 90°.

Answer:

b. ∠GFH, ∠CFE
