In order to apply the law of cosines to find the measure of an interior angle what is enough to know?
The lengths of all three sides of the triangle APEX:)
If two sides of a triangle are of equal lengths what does that say about the angles opposite those sides?
The base angles of an isosceles triangle that has two equal sides are equal.
How can you measure angles without using a protractor?
The answer will depend on what other information you have. If, for example, the angle is in a triangle, and you know the lengths of all three sides, you can use the cosine rule.
Does 6 8 10 make a triangle?
Yes. The side lengths of a triangle may measure 6, 8, and 10. It satisfies the triangle inequality (the sum of any two sides is greater than the third). Moreover, it forms a multiple of the common 3-4-5 right triangles.
If two angles of a triangle each measure 54 What is the measure of the third angle?
If two angles of a triangle each measure 55 what is the measure of the third angle?
When do you use the Law of Cosines?
We use the law of Cosines to be able to find : 1. The measure of the third side, when the measure of two sides and the included angle of a triangle ABC are known. 2. The measure of any angle, when the measure of the three sides of a triangle ABC are known.

When do you use law of sines and law of cos sines?
Use Law of Sines if you know:Two angle measures and any side length orTwo side lengths and a non-included angle measure.Use Law of Cosines if you know:Two side lengths and the included angle measure orThree side lengths.
A triangle with 2 side lengths of equal measure?
that's an iscoceles triangle...
What are the kinds of triangle according to measure of sides?
An isosceles triangle has 3 sides 2 of which are equal in lengths An equilateral triangle has 3 sides all of which are equal in lengths
How do you measure triangle?
It depends on what you wish to measure: the lengths of sides, the angles, the area, the perimeter.
How do you work out the lengths of each side of an equilateral triangle?
Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.
How do you find the measure of a triangle with 3 different measures?
Too broad of a question... What measure are you talking about? angles? side lengths?
How do you calculate square meter of tringle?
It depends on what information you do have about the triangle. There are different equations depending on whether you know the lengths of three sides, the lengths of two sides and the measure of the included angle, the length of one side and the perpendicular distance to the other vertex (base and height).
How do you find the side lengths of the lengths a and b on a triangle?
It depends very much on what information is given. In the last resort, you just get a ruler and measure them!
Why will 3 lengths of equal measure always form a triangle?
Well if your talking about a regular triangle (equilateral triangle) it is because if you measure it then it will always equal 60 degrees on each turn. Which then Equals 180 (This is for all triangles).
What are the leg lengths of a triangle with a hypotenuse of 8?
do you have an angle measure? (if it is an equilateral triangle all legs will be 8 but i don't think this applies in your case)
