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.
