No, right angles are 90 degrees, supplementary and vertical angles are 180 degrees.
Two opposite right-angles, whose corners share the same crossing point, are vertical angles.
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
no
A line that is at right angles to a vertical line is said to be horizontal.
I think you mean vertical angles. Vertical angles are formed by two intersecting lines that make what looks like an X. Vertical angles are the two angles that are across from each other, either the top and bottom 2 angles or the left and right 2 angles. Vertical angles are also always congruent!
vertical angles are when you have an "x" made by intersecting lines and the angles in it are vertical angles. Opposite angles are when you have the x, the angles are on directly opposite sides. --->x<--- those are opposite of each other. therefore they are opposite angles. the arrows are pointing at them
vertical; straight up and down; upright; meeting a given line or surface at right angles.
Sure, as long as the two intersecting lines are perpendicular.
Supplementary.
ya, they're perpendicular lines
The term parallelogram refers to a four sided geometrical figure (in other words, a quadrilateral) in which there are two sets of parallel sides. The angles can vary; they can be right angles, or they can be acute or obtuse angles, as long as there are two sets of parallel sides. Angles are not said to be vertical to each other. Angles can be perpendicular to each other, but not vertical or horizontal. If angles are perpendicular, then they are right angles, in other words, 90o angles. Lines can be vertical, but angles can't.
