Acute angles (less than 90 degrees)
Obtuse angles (greater than 90 degrees)
Right angles ( equal to 90 degrees)
Quadrant angles are the angle lies in different quadrants. The angles which lie between 0° and 90° are said to lie in the first quadrant. The angles between 90° and 180° are in the second quadrant, angles between 180° and 270° are in the third quadrant and angles between 270° and 360° are in the fourth quadrant Quadrant angles are the angle lies in different quadrants.

It's possible that either the angles or sides are labeled according to length or size.
A trapezium has 4 right angles...Correction: it has 4 angles but they are not right angles. A structure/shape with 4 right angles is a rectangle or square.
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
The other 2 angles will be acute and the 3 angles altogether will add up to 180 degrees
A square and a rectangle for example.
"How are straight angles different from right angles?" Is this a statement?
That depends, what it is you know. For example, if you know two of the angles, you can use the rule that the sum of the three angles must be 180 degrees. If you know the sides, the calculation is different, and involves trigonometry.
Yes as for example a scalene triangle can have 3 different acute angles that all add up to 180 degrees
Yes. For example a quadrilateral can have angles 80°, 85°, 95°, 100 The only requirement is that the sum of the 4 angles is 360°.
One example would be a triangle. A triangle has three angles.
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
congurent angles are angles that have equal angles. Example, if you want to have equal angles, you have to have a shape that has equal sides
You beat them.
There isn't any. Dilations do not affect angles.

A 4 sided polygon is called a quadrilateral. Depending on where the two right angles are, would put the quadrilateral into different subsets. For example if the two right angles are on adjacent corners (and the other 2 angles are not right angles), then it is a trapezoid. If the 2 right angles are in opposite corners, and the other 2 angles are not right angles then it would be a kite-shaped quadrilateral.
