quadrilaterals are consecutive and opposite angles always congruent?
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 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.
always
It is a rectangle.
Angles that are always congruent are applesauce angles
All right angles are congruent, and all straight angles are congruent.
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
yes
Opposite angles are congruent in a parallelogram.
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
the shape? no, not always. but they are always at least similar figures. but the angles alone are always congruent
quadrilaterals are consecutive and opposite angles always congruent?
A rhombus always have 2 pairs of congruent angles, yes.
right angles
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
Parrelle lines are congruent. Think of a square and its angles(;
