What is vertically opposite angle?
Vertically opposite angles are the angles that are formed when two lines intersect. When the lines cross, they create two pairs of opposite angles that are equal in measure. For example, if two lines intersect and form angles of 40 degrees and 140 degrees, the angles across from each other (the vertically opposite angles) will both be 40 degrees and 140 degrees, respectively. This property is a fundamental concept in geometry.
What are the quadrant angles?
Quadrant angles are angles formed in the coordinate plane by the x-axis and y-axis. Each quadrant is a region bounded by the x-axis and y-axis, and is numbered counterclockwise starting from the positive x-axis. The angles in each quadrant have specific characteristics based on their trigonometric ratios, such as sine, cosine, and tangent values. In trigonometry, understanding quadrant angles is crucial for determining the sign of trigonometric functions and solving equations involving angles.
When doing trigonometry for example the cosine rule how do you know which side is a which side is b and which side is c if none of them are marked on and neither are the angles?
It's possible that either the angles or sides are labeled according to length or size.
How many angles are there in a trapezium?
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.
What is the difference between angles of trigonometry and angles of geometry?
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
Two polygon that have equal angles but different size?
A square and a rectangle for example.
Is how are straight angles different from right angles a statement?
"How are straight angles different from right angles?" Is this a statement?
How to wokout triangle angles?
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.
What is an example of number of angles?
One example would be a triangle. A triangle has three angles.
Can a triangle have all acute angles and not be an equalateral triangle?
Yes as for example a scalene triangle can have 3 different acute angles that all add up to 180 degrees
Can a quadralateral have 4 angles of different measure?
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°.
What is congurent angles?
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
What is a counter example for the statement congruent angles are always vertical 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.
What is an example of dilation in angles?
There isn't any. Dilations do not affect angles.
How do you expain measuring angles in degrees to kids?
You beat them.
How are acute angles different from obtuse angles?

Does a polygon usually have more sides or more angles example?
A polygon has an equal number of sides and angles. For example, a triangle has 3 sides and 3 internal angles.
