What are some examples of complementary angles?
ANY two angles that total 90o, eg the "other" angles in a right-angled triangle.
What figure has four right angles and any types of angles?
A polygon with six or more sides, in which four of the angles are right angles and the other angles are not. These others are of any type - as required. It cannot be a pentagon because, if 4 angles are right angles, the fifth would be 180 degrees!
Two pairs of consecutive angles are supplementary?
No, these are two quite different things. "Supplementary" means that the sum of the angles is 180 degrees. The angles need not be consecutive; on the other hand, two consecutive angles can have any measure, not always 180 degrees.No, these are two quite different things.

How many equal angles can a right triangle have?
A right triangle can have 2 equal angles if they are each 45° (any other right triangle will have no equal angles)
What is unique about adjacent angles?
Adjacent angles are simply two angles that are next to one another and share one side. There is nothing else unique about these angles, and they are measured as one would measure any other angles.
How do you find the size of f angles?
The answer depends on your knowledge of any of the other angles in the intersections.
What are the angles in trigonometry?
Angles in trigonometry are the same as any other angles. They are a measure of the separation between two lines which meet at a point.

How is a rectangle different for a other quadrilateral?
Rectangles have only right angles (9o degrees angles) whereas other quadrilaterals can have any kind of angles, as long as they have 4 sides.

How can I show that the angles are congruent without measuring the angles?
You would have to be given other information about the angles that would let you deduce that they are equal. For example any two right angles are equal. If two parallel lines are cut by a transversal, the alternate interior angles are equal.
Why does a triangle have at least 2 acute angles?
It is impossible for a triangle to have one or no acute angles because all three angles must add up to 180 degrees. If only one angle was acute, the other two angles would be required to be obtuse or right angles, and any combination of these other two angles would add up to 180 degrees or higher (minimum two right angles). For this reason, it is possible to only have one obtuse angle or one right angle in any triangle, making the other two angles acute by definition.
How many angles does a trapezium?
A trapezium has 4 internal angles and 4 external ones, just like any other quadrilateral.
