Yes.
Yes
yes, intersecting lines form two pairs of congruent angles
If all adjacent angles are congruent, it can only be a rectangle (or square).
Rectangles have congruent adjacent angles.
perpendicualr lines form 90 degree angles and intersecting lines just insersect. perpendicular: _ l _ intersecting: x l
Whenever two lines intersect, vertical angles refers to the angles opposite each other
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
Adjacent angles
That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
Yes
Rectangle: A quadrilateral with 4 right angles, diagonals congruent/bisecting, and opposite sides congruent, BUT ADJACENT SIDES ARE NOT CONGRUENT. Rhobus: A quadrilateral with opposite congruent angles, but adjacent angles are Not congruent, perpendicular bisecting diagonals and 4 congruent sides. Square: A quadrilateral that is a rectangle and a square with 4 right angles, diagonals congruet/bisecting that ar perpendicular, and opposites sides congruent.
yes
Rhombus' Congruent AnglesIt's not the adjacent angles of a rhombus that are congruent, but the diagonal ones.
yes, intersecting lines form two pairs of congruent angles
If all adjacent angles are congruent, it can only be a rectangle (or square).
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
Yes. Perpendicular lines are intersecting lines, but they have right angles.
