Yes, according to vertical angle theorem, no matter how you throw your skewers or pencils so that they cross, or how two intersecting lines cross, vertical angles will always be congruent, or equal to each other. Vertical angles are congruent. Score .9081 User: If three parallel lines are cut by a transversal and one angle is measured to be 90°, what can be said of the remaining angles?A. For example, look at the two angles in red above. never. How do you think about the answers? Vertical angles. Given that angle 2 and angle 4 are vertical angles, then there is an angle between them, looks like angle 3 , so that angle 2 and angle 3 are linear pairs and angle 3 and angle 4 are. These are called vertical angles, on opposite sides of p. By the same reasoning, w and y are vertical angles, and are congruent. Theorem: Vertical angles are congruent. Proving angles are congruent. Vertical angles are always congruent - they always have the same angle measure. are vertical angles sometimes always or never supplementary? So the answer would be sometimes. Math. STUDY. 1. Vertical angles are always equal. When two lines intersect the opposite angles form vertical angles or vertically opposite angles. So vertical angles always share the same vertex, or corner point of the angle. They are called vertical angles because they share the same vertex.
