a trapezoid
intersecting lines * * * * * Non-perpendicular intersecting lines. Or else the angles would be right angles.
acute and obtuse.
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
None because it has 2 equal obtuse angles and 2 equal acute angles but its diagonals intersect each other at right angles
there are 4 types of common angles. right, obtuse, acute, and straight.
Acute, obtuse, or 90 degree (right) angles.
Non-perpendicular intersecting lines.
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.
They will be acute angles.
No, an obtuse triangles has one obtuse angle and two acute angles. If a triangle has an obtuse angle, it is considered obtuse and cannot be acute.

acute and obtuse.
They make a pair of acute angles and a pair of obtuse angles. In rotational order, the angles are acute, obtuse, acute, obtuse.
A rectangle has no acute angles and no obtuse angles. It has 4 right angles.
None because it has 2 equal obtuse angles and 2 equal acute angles but its diagonals intersect each other at right angles
Vertical equal opposite angles are formed when lines intersect each other.
