The sum of all the angles of a triangle?
The sum of all the interior angles of a triangle is 180 degrees while the sum of the exterior angles is 360. you can calculate for the measurements of the interior angles of a polygon by using the formula S=(n-2)(180) where n is the number of sides
How do you find angles in a triangle using only the lengths?

How do you find the measure of a angle on a triangle?
You can measure it. Or you can calculate it based on something else you know about the triangle; for example: * If you know the measures of the other two angles, use the fact that the sum of all three angles is 180°. * If you know the length of all three sides, you can find the angles using the law of cosines. Or basic trigonometry, if you also know that one of the angles is a right angle. * If you know something else about the triangle, you may or may not have enough information to calculate the measure of an angle. In that case, I suggest you ask a specific question, stating what you know.
How can you classify triangles using angles and using sides?
Using angles and sides:All three angles equal. This implies that all three sides are of the same length. The triangle may be known as an equiangular triangle but, more commonly, equilateral triangle.Two equal angles, which implies that two sides are equal. The triangle is an isosceles triangle.All three angles (and therefore sides) are different. This is known as a scalene triangle.Using angles only:If all angles are less than 90 degrees it is an acute angles triangle.If one angle is 90 degrees, a right angled triangle.If one angle is greater than 90 degrees then an obtuse angled triangle.

Uses of six trigonometry functions?
The trigonometric functions give ratios defined by an angle. Whenever you have an angle and a side in right triangle, you can find all the other angles and sides using the six trigonometric functions and their inverses. The link below demonstrates the relationship between functions.
How do you know the measure of each angle in an equilateral triangle using what you know about equilateral triangles and the degree measure of a circle or a straight angle?
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°

How do you know what angles in a triangle are worth using algebra?
If the triangle is equilangular, then all angles are 60 degrees: 180/3 = 60 If the measures of two angles are given, you can discover the 3rd one by subtracting the sum of the two angles from 180.
If the only information given about an oblique triangle is the lengths of the three sides which method should you use to solve for the angles?
By using the cosine rule in trigonometry the angles of the triangle can be worked out.
How do you calculate the angles in a triangle?
The angles in a triangle add up to 180 so one can calculate depending on the type of question or information given. For example;when one is given a scalene triangle, one can calculate the missing angle by equating all the angles to 180 and then find the missing one.
Is a right triangle can be isosceles?
Yes. Only if the other two angles of the right triangle are congruent and each equal 45 degrees. Then using the isosceles triangle theorem, you know that the two sides opposite the angles are congruent.
