What is different between 1st angle and 3rd angle?
Basically its just where you position the views of the main object, in first angle projection, if you view the object from the left, the view is drawn to the right of the object, in third angle projection, its drawn on the viewing side.
What is the advantage of measuring the angle of reflection and angle incident on either side of the normal to the surface of the mirror?
We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles on the either side of the mirror.
What is the mathematical definition of angle of elevation?
The angle of elevation is defined as the angle formed between a horizontal line and the line of sight to an object that is above the horizontal line. It is measured from the observer's eye level up to the object. In mathematical terms, it can be expressed using trigonometric functions, where the tangent of the angle is the ratio of the opposite side (the height of the object) to the adjacent side (the distance from the observer to the base of the object).
What is the type of congruence between the triangles shown?
side- angle- side
What does it mean for a side or angle to be included?
The 'included side' is the side between the two given angles. The 'included angle' is the angle between the two given sides.
Is angle-angle-side a correct property of concurrency of triangles?
As long as the sides correspond then yes. The other three are: Side-Side-Side Side-Angle-Side - the angle *MUST* be between the two sides Right angle-Hypotenuse-Side
The set of all points between the side of an angle?
interior of an angle
How many different quadrilaterals have exactly 2 congruent side's?
The answer depends on two side's what!If you meant two sides, then there are infinitely many quadrilaterals - each different angle between the sides will give a different shape.
In a scalene triangle, the longest side is opposite the angle with the smallest measure?
In a scalene triangle, each side has a different length and each angle has a different measure. The longest side is always opposite the largest angle, while the shortest side is opposite the smallest angle. Therefore, the statement that the longest side is opposite the angle with the smallest measure is incorrect; it should be the opposite.
What is the name for the angle between the top and side of an open box?
An obtuse angle.
What describes the angle between the top and side of an open box?
An obtuse angle
What are the 5 shortcuts used for proving triangles are congruent?
I only know 3. SSS (side/side/side) -> if all three sides are the same length SAS (side/angle/side) -> if two sides and the angle between them are the same ASA (angle/side/angle) -> if two angles and the side between them are the same
