yes or no
yes
That they are congruent.
vertical angles Congruent
the shape? no, not always. but they are always at least similar figures. but the angles alone are always congruent
Oh, dude, proving vertical angles are congruent? That's like proving water is wet. Helena just needs to show that those angles are opposite each other when two lines intersect. It's like saying, "Hey, these angles are equal because they're like mirror images of each other." Easy peasy lemon squeezy.
yes
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
vertical angles
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
That they are congruent.
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
yes or no
not all congruent angles are vertical angles. Vertical angles must share a vertex.
Vertical angles are not always complementary. In some cases, they will congruent and supplementary which makes them add up to 180 degrees.
Yes, intersecting chords do form a pair of congruent vertical angles. When two chords intersect, they create two pairs of opposite angles, known as vertical angles. According to the properties of vertical angles, these angles are always congruent to each other. Therefore, the angles formed by intersecting chords are equal in measure.
