Yes
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.
Perpendicular lines formed right angles.
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
right angles
square

Yes.
yes
false
Only if the angles formed are right angles otherwise they form vertical opposite equal angles

No. Perpendicular lines for right angles. That is why they are called perpendicular.
A rectangle's perpendicular lines are ALWAYS adjacent to eachother
If two lines intersect at right angles then they are perpendicular!
Perpendicular lines formed right angles.
