Is up and down perpendicular?
NO!!! Perpendicular means a line is at right-angles( 90 degrees) to anotyher line. 'Up & 'Down' are the directions of movement in a vertical maNNER.
What are 3 attributes of a triangle?
all the lines on a triangle are equal and the opposite sides are parallel
Adjacent angles add up to be 90 degrees?
No. Complementary angles add up to 90 degrees. Supplementary angles add up to 180 degrees.
What do all the angles add up to in an 5 sided shape?
Interior angles add up to 540 degrees Exterior angles add up to 360 degrees
Two angles that add up to 180?
Two angles that add up to 180 degrees are called supplementary angles.
What intersecting lines are not perendicular?
Lines are perpendicular when they form a 90-degree angle so if the angles of two lines don't add up to 90, they are not perpendicular.
How does a square have perpendicular lines?
Right angles are made up of perpendicular lines. A square has four of them.
Are alternate exterior angles on parallel lines ever supplementary?
Only if they add up to 180 degrees which would be the case if the parallel lines are cut through by a perpendicular line.
Is angles in parallel lines supposed to add up to 360 degrees?
Parallel lines do not meet. Therefore they do not form any angles! So the angles (that do not exist) cannot add up to anything.
How many perpendicular sides are in a rectangle?
It has 4 perpendicular sides creating 4 interior right angles that add up to 360 degrees
What do angles in a trapezium add up to?
The internal angles add up to 360 degrees. If the trapezium has its base parallel to the top then the internal angles on the left of the parallel lines add to 180 degrees, the angles on the right add to 180 degrees.
What do vertical angles add up to?
A vertical angle is perpendicular to a horizontal base and equals 90 degrees
What do all the angles on a perpendicular line add up to all together?
i dont know but i think 360
What is the sum of the measures of the four angles formed by intersecting lines?
The angles will add up to 360 degrees
What is the sum of the measures of four angles formed by intersecting lines?
The angles will add up to 360 degrees
Can two acute angles have perpendicular sides?
Yes. If the two acute angles have their measures add up to 90 degrees, and both angles share one side that is common to each angle (they are adjacent), then their non-common sides will be perpendicular.
What describes angles formed by 2 intersecting lines?
Opposite angles are equal. Adjacent angles add up to 180 degrees.
