Step-by-step explanation:
Sure thing! The first thing we need to do is draw a diagram of the intersecting chair parts, so that we can see the angles more clearly. Let's call the angles A, B, C, and D, where A and B share a ray, B and C share a ray, and C and D share a ray. Now, let's look at the pairs of angles that share a ray. Angle A and angle B share the ray AB, so they are a pair of angles. Angle B and angle C share the ray BC, so they are also a pair of angles. Angle C and angle D share the ray
