No but a right angle is a perpendicular
No.
Vertical angles can be acute, right (if the intersecting lines forming them are perpendicular) or obtuse.
No but a right angle triangle has perpendicular sides and an hypotenuse.
Like __/ or \__. (in between a straight line and a right angle (perpendicular lines)
an obtuse angle slightly more than 90. Angles are not quite perpendicular.
In the same way that you bisect an acute triangle. Alternatively, you could extend one of the rays of the obtuse angle so that you have an acute angle. Bisect that angle and then draw a perpendicular to the bisector of the acute angle through the vertex.
They can but don't have to as long as they are intersecting it doesn't matter whatt type of angles they form. * * * * * NO! The fact that they are perpendicular means that they intersect at right angles. Not an acute angle, not an obtuse angle but a right angle. That is what perpendicular is.
It is an obtuse angle. It is an obtuse angle. It is an obtuse angle. It is an obtuse angle.
NO, because each intercecting line does not make a right angle-some could make acute or obtuse angles. To be perpendicular the lines that meet have to make a right angle(90 degree angle) or else they will not be perpendicular.
An obtuse angle.
A obtuse angle is called an obtuse angle because if obtuse means bigger in degrees and a right angle is 90 degrees than a obtuse angle must be over 90 degrees.
An obtuse triangle has an obtuse angle.
