They are adjacent angles.
A kite probably has no right angles.
not all congruent angles are vertical angles. Vertical angles must share a vertex.
have the same vertex. be congruent.
The sum of the angles around a vertex point in a plane will always be 360o. Picture a bicycle wheel with all its spokes radiating out from the hub. Now pick two spokes to form a vertex. Find the angle of your vertex, and then subtract it from 360o. As there are 360o in a circle, and your figure (the vertex) is a slice of the circle, its angle plus all the rest of the arc about the vertex will sum to 360o. If you've discovered the angle of your vertex, you cannot help but find the sum of the rest of the angles (if there are more than one) around your vertex.
Not necessarily
The top and bottom angles - the angles that are between the pairs of congruent sides. They are opposite each other and not necessarily congruent.
Non-existent in ordinary shapes.
Adjacent angles.
A quadrilateral that could have a 45-degree vertex angle is a kite. In a kite, the two pairs of adjacent sides are congruent, and one pair of opposite angles is congruent. Therefore, if one of the angles is 45 degrees, the opposite angle would also be 45 degrees. This makes a kite one of the quadrilaterals that could have a 45-degree vertex angle.
A kite has 4 right angles (all angles of the kite are right angles), since the kite is parallel. If the kite was cyclic, then 2 right angles. And if normal kite, then 0 right angles.
Those are a pair of 'supplementary' angles.
it has a number of faces, vertex and edges -- The angles are not all the same
Where two straight lines cross the "vertically opposite" angles are equal.
A kite (quadrilateral) has a pair of opposite angles which are the same measure. The diagonals are perpendicular, so you can divide the kite into four right triangles, and solve for those if you're given some dimensions. The diagonal, which connects the two congruent (same) angles, will be cut in half (bisected) by the other diagonal.
If two angles do not have a common vertex they cannot be adjacent angles.
Adjacent angles are defined as angles that share a side and a vertex point. A vertex is a corner point.
