Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
If two lines intersect at right angles then they are perpendicular!
By definition, perpendicular lines form right angles.
90 degree angles.
no, they have congruent angles
No. Perpendicular lines for right angles. That is why they are called perpendicular.
No sides perpendicular means no right angles. A rhombus is a quadrilateral with no right angles so no sides perpendicular.
yes it is A trapizium has no right angles therefore there are no perpendicular.* * * * *Nonsense! A trapezium can have two adjacent angles which are right angles.
Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
If two lines intersect at right angles then they are perpendicular!
right angles
Yes, all perpendicular angles form 90 degree angles.
Perpendicular
no
Two straight lines that meet at right angles are perpendicular.
By definition, perpendicular lines form right angles.
What is a 'Straight Angle'???? Perpendicular lines meet at 90 degrees ( right- angles).
