Yes.
a lozenge 4 angle two diagonal angle form and obtuse angle and the total are 180 degrees.
Any triangle with one angle in the range (90, 180) degrees and the other two angles adding up to its supplement will form an obtuse triangle.
A reflex angle is one that is greater than 180 degrees (a straight line) but less than 360 degrees (a full circle). When two lines meet (not cross), they will form two angles. Unless they meet head on, one of these will be less than 180 degrees and the other will be more; the two of them will add to 360 degrees. Conventionally the smaller of the two angles will be used as a measure of the angle. The reflex is the larger of the two.
Yes in the form of obtuse angles or reflex angles

Yes.
Not always because an obtuse angle is greater than 90 but less than 180 degrees

An line that is not perpindicular to the other line makes an acute or obtuse angle Oblique lines are not parallel or perpendicular which would be lines that form acute or obtuse angles at the point of intersection.
Of course not !Stick a 2° angle onto a 4° angle and you still have only a 6° angle.
They appear to be 45 degree angle, on the top and bottom angle and will be classes as acute angles as they are less than 90 degrees (a right angle) the left and right angle of the X would be classed as obtuse angles as it can be clearly seen that their angle is more than 90 degrees. The exact amount of degrees of each angle would be slightly difference depending on if it was handwritten or whether it was typed on a computer where it would have a fixed code to preset it in image form.
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.
Triangles are either accute, obtuse, or right. To draw an accute triangle start by drawing an accute angle (less than 90 degrees). Then extend the ends of the angle and connect them making sure that both new angles are also acute. To draw a right triange first draw a right angle. Then extend the angle and connect to form two accute angles. To draw an obtuse triangle first draw an obtuse angle (greater than 90 degrees). Then extend the sides of the angle and connect creating 2 accute angles.
Roads don't always form an acute angle, they can form a right angle. If you are really picky, you might say that they can never form a perfect right angle, so two of the angles formed must be acute (and the other two obtuse).
