can adjacent angles be vertical?
532003
Vertical angles are also known as vertically opposite angles which means they share the same vertex and are formed when two lines cross. Hence they are not adjacent (side by side) but opposite!!

When two lines intersect they form two pairs of opposite angles, A + C and B + D. Another word for opposite angles are vertical angles. Vertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex.

On a rectangle, consecutive angles are not supplementary. On a rectangle, diagonals bisect each other. On a rhombus, all four sides are congruent. On a rhombus, diagonals are not perpendicular.

['AAA (angle angle angle) All three pairs of corresponding angles are the same. ... ', 'SSS in same proportion (side side side) All three pairs of corresponding sides are in the same proportion. ... ', 'SAS (side angle side) Two pairs of sides in the same proportion and the included angle equal.']

Alternate angles form a 'Z' shape and are sometimes called 'Z angles'. a and b are adjacent angles. Adjacent angles add up to 180 degrees.

Answer and Explanation: Yes, adjacent angles can be complementary. Complementary angles are defined as two acute angles with a sum that is equal to 90°.

Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) ∠1 and ∠2 are adjacent angles. ... A Linear Pair is two adjacent angles whose non-common sides form opposite rays.

"Vertical" refers to the vertex (where they cross), NOT up/down. They are also called vertically opposite angles. Try moving the points below. Notice that the 4 angles are actually two pairs of vertical angles: See: Vertex.

Angles which share a common vertex and are opposite each other in the four angles formed when two lines intersect are called vertical angles. ... 5) Angles A and B are adjacent because they share vertex b and side bc.

Alternate angles are always equal. Corresponding angles are always equal. Allied (or co-interior) angles are supplementary. Vertically opposite angles are always equal.

Alternate angles form a 'Z' shape and are sometimes called 'Z angles'. a and b are adjacent angles. Adjacent angles add up to 180 degrees. ... d and f are interior angles. These add up to 180 degrees (e and c are also interior).

Vertical angles are angles that are opposite each other when two lines intersect each other. The two pairs of opposite angles are equal to each other. The two pairs of neighboring angles are supplementary, meaning they add up to 180 degrees. ... These two angles can be located anywhere.

When two lines intersect to make an X, angles on opposite sides of the X are called vertical angles. ... Finally, angle 3 and angle 6 are congruent vertical angles, so angle 6 must be 145° as well.

Adjacent angles are two angles that have a common vertex and a common side but do not overlap. ... In the figure, ∠1 and ∠3 are non-adjacent angles. They share a common vertex, but not a common side. Angles ∠1 and ∠2 are non-adjacent angles.

Notice that, like the alternate interior angles, these angles are not adjacent. are equal in measure. If two parallel lines are cut by a transversal, the alternate exterior angles are congruent. If two lines are cut by a transversal and the alternate exterior angles are congruent, the lines are parallel.

No, because if two consecutive angles are supplementary, then another pair of consecutive angles are also supplementary. Since a kite has one pair of congruent opposite angles, then two pairs of opposite angles must be congruent.

Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles.
