When can you use the sine law?
The tricky part of the law of sines is knowing when you are able to use it. Whether you can use the law of Sine's or not depends on what information you have or were given. In some cases the information you were given could make two different triangles. There are three times when you can use the law of sines. One example of when you can use it is when you have the length of a side and the measures of both the angles that that side is adjacent to. This is called angle side angle or asa for short. Another time when you can use the law of sines is when you are given the measures of two angles and a side that is outside the angles. This is called aas. Finally the last case where you can use the law of sines is when you have two side lengths and the measure of an angle. Math teachers refer to this one as ssa, I remember that this one is special. If you are given the measure of an angle and two sides you could have two different triangles.
You and rsquore given side AB with a length of 6 centimeters and side BC with a length of 5 centimeters. The measure of angle A is 30 and deg. How many triangles can you construct using these measurem?
You're given side AB with a length of 6 centimeters and side BC with a length of 5 centimeters. The measure of angle A is 30°. How many triangles can you construct using these measurements?
What Two angle measures of this triangle are 60 and deg. Which type of triangle is it?
An equilateral triangle would fit the given description
How many triangles exist with the given side lengths 4m 4m 7m?
A triangle with two equal sides is an isosceles triangle and you can have as many as you like.
How could you use symmetry to find side lengths and angle measures of a geometric figure?
The answer will depend on the figure, the type(s) of symmetry and what information about is is given.
How many triangles exist with the given angle measures 30 and deg 65 and deg 85 and deg?
As many as you like but they will all be scalene triangles from the given interior angles that add up to 180 degrees.
How many triangles exist with the given angle measures degrees 45 degrees and 90 degrees?
As many as you like because any triangle that has a 90 degree angle is always a right angle triangle.
Which triangles angle measures 32 degrees 79 degrees and 69 degrees?
It is a scalene triangle that would have the given angles.
How do you find out the height of a triangle if only the 3 angles are given?
It is impossible to find a triangle if only angle measures are given (all similar triangles have the same angles).
How many triangles exist with the given angle measures 55 degrees 45 degrees 90 degrees?
No triangle exists with the given angle measures. None because the given angles add up to 190 degrees and the 3 angles in any triangle add up to 180 degrees.
What is the relationship between the number of triangles and the sum of the angle measures of the polygon?
In a polygon with n sides, the sum of the interior angles is given by (n-2) * 180 degrees. Each triangle has interior angle sum of 180 degrees. Therefore, the number of triangles that can be formed in a polygon is equal to (n-2) * 180 / 180, which simplifies to (n-2). In other words, the number of triangles is two less than the number of sides in the polygon.

SSA does not guarantee congruence between two triangles?
True. Only if the given angle is between the two sides will the two triangles guarantee to be congruent (SAS), unless the given angle is a right angle (90°) in which case you now have RHS (Right-angle, Hypotenuse, Side) which does guarantee congruence.
What are facts about right triangles?
The ratio of the length of the side opposite a given angle to the hypotenuse is the sine of that angle.The ratio of the length of the side adjacent to a given angle to the hypotenuse is the cosine of that angle.The ratio of the length of the side opposite a given angle to the side adjacent to that angle is the tangent of that angle.
